Understanding The Functions Of A Proxy Server

In a network of computers, an application program or the computer system will function as a server. It acts as a link to get the information required from the other servers by the user of the computer. The client or the user will be connected to the proxy server when he requests for a file or a connection or a web page or any other details that are available from the other server. The request of the client is evaluated by the proxy server based on the rules of filtering.

For example, the proxy server may filter the traffic based on the protocol or the IP address. If the proxy server validates the request according to the filter, then it offers the resource by just connecting it to the concerned server and pass on the request for the service on clients behalf. The proxy server has also got the option to alter the request of the client or the response of the server and in many cases the request is served without any communication to the particular server. Instead, in this circumstance, it caches the reply from the remote server and forwards the further requests direct with regard to the same matter.

The proxy server has got two purposes. One is that it keeps all the computers behind it as anonymous mainly for the purpose of security. The next one is that it speeds up the access to the resource through caching. It is popularly used just for the purpose of caching the web pages from the web server.

The proxy server also passes the replies and the requests without any modification and is generally called as the gate way. It is also otherwise called as the tunneling proxy.

The proxy server can be located in the local computer of the user or even at different points between the source servers and the user or in the internet. The reverse proxy is a type of proxy that is utilized as a front end to speed up and cache the resources in demand like web page.

Although there are various uses that can be obtained from the proxy servers, the most important one is that it reduces the cost of the hardware. A company may be in possession of many computers that are connected on the same network or may be even under the control of one server and thus does not allow all the computers to have the connection to the internet directly. Under these circumstances, each and every computer under the same network can be connected to a single proxy server and in turn the proxy server will connect the computers to the main server for access to the internet.

Sql Server Database Corruption If You Run A Query With Parallel Execution Plan

You may come across Access Violation if you run an SQL query, which uses parallel execution plan in Microsoft SQL Server 2008. Access violation is an error condition, which may occur while performing general operations on the SQL database. It may occur due to application malfunction, software bug, or database corruption. It renders your database inaccessible and may cause data loss, if you don’t have a complete backup to restore data from. To overcome such issues, is required.

As an example of Access Violation in Microsoft SQL Server 2008, consider the below scenario:

In MS SQL Server 2008, you’re running a query that includes all the below mentioned clauses:
Inner join
Union all
Group by
The database query is using parallel execution plan.
You execute the query.

In the above scenario, you may face access violation. And, you receive the following error message:

Location: xbmp.cpp:2038
Expression: 0 != pxteBitmap
Msg 3624, Level 20, State 1, Line 2
A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a QFE from Technical Support.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.

Furthermore, the mini-dump file is returned under the log folder of MS SQL Server 2008.

Cause

As sated in the above error message, this problem may have occurred due to either database corruption or a software bug. After corruption, SQL Server can not read the database and this behavior occurs.

Resolution

Run DBCC CHECKDB utility to try fixing database corruption. If the database is severely corrupted, it may not work. In such cases, third-party applications are worth using.

The MS SQL Recovery applications are particularly designed to thoroughly scan whole SQL Server database and extract all damaged and inaccessible objects from it. They allow you to perform SQL Recovery on your own as they have simple and rich graphical user interface.

SQL Recovery software safely and successfully repairs damaged SQL Server database in all cases of corruption. It works well with Microsoft SQL Server 2008, 2005, and 2000. The software restores all database objects such as tables, reports, forms, macros, and more.

What Is Actual Working Of Proxy Server

The most common and popular way to stay on internet nameless is proxy server. To accept incoming request of web and forward it to destination are done by the proxy server machine; these severs acts like a middle men of internet which assist to distinguish your computer and destination server. Each computer get connected to net through proxy server or it is a computer that offers online as well as offline services to permit other system users to use web world. So proxy server serve the role of agent between the client (users computer) and server.
Please dont mix up the concept of a proxy server with a NAT (Network Address Translation). Although they look alike, a proxy server does the work of connection, response, and receives traffic from the Internet. In other words, it acts in support of the client computer. A NAT, on the other side, it changes the original address of traffic coming through it and passes it to the Internet. The computer after the NAT, not the NAT itself, does the work.

Technically the difference between proxy server and NAT is as proxy server use transport level 4 or higher, but NAT using 3rd level.
How It Works:
1.When a user on intranet requested for any web page. Actually it requests to proxy server, which forward it to destination server. It also receive data from net server before the client pc, and it transmits the data to user.
2.Proxy servers maintain log report of total network usage such as download, IP address of accessed websites, date & time of access, URL. E.g. Telnet proxy server can trace each and every data passing through.
3.Some proxy servers have to work with unique users. Many people use Netscape with proxy servers. When such type of software is used, that software must be configured to use it with proxy server. Then only intranet users allow using client software as usual.
4.Proxy server not only work as relay but also it can make secured network in office, home. E.g. a FTP proxy server can configured to restrict any type of miss use, means ban download or upload or both.
5.Proxy server also served as time saver. It keeps the copies of web pages .So when user request for same, proxy server provide that page without contacting to internet server. It save time when time is main factor of work.

Differences Between Dedicated Server, Cloud Computing And Vps

Many people still do not know or are confused when speaking of the major differences between Cloud Server Hosting, Virtual Private Servers (VPS) and Dedicated Servers. Starting with the most basic, you know what to serve?

Quite simply, all the three technologies are used to store data, host websites and structures of e- mail, besides running various applications and softwares. So if they serve for the same thing because they are different?

Each has a different characteristic, let us understand :

Dedicated Servers

It is a physical machine, usually allocated on a fully equipped data center and is totally dedicated to one customer who requires high reliability and high performance hardware ( processing, memory , etc.)… If the client needs more resources, you must purchase more hardware and manually install or exchange server. Its main advantage is the high performance and flexibility and its disadvantage is the high price and inability to upgrade / downgrade immediately. This is one of the best flexible solution than shared web hosting, as because the owner gets a total control over the hosting environment and every aspects of the dedicated hosting, which includes the selection of operating system, server hardware, etc… Some web hosting providers may provide the server administration for free, but usually, the client has to manage the server administration and management tasks.

Cloud Server Hosting (Cloud Computing)

Already Cloud Server is a fractionation of a number of resources available to multiple servers and storage arrays. Through an intelligent architecture, you can allocate these resources allows scalability without losing performance. Besides the economy and flexibility, there are numerous advantages to this technology.

Virtual Private Servers (VPS)

It is the fractionation of resources from one physical server, this fractionation being allocated to a single client. VPS is an ideal choice for businesses that requires same flexibility, reliability, security, root access, stability, etc… at much affordable rates that a dedicated server offers. In this technology there is no guarantee of processing and in case of hardware failures, client applications that depend on it will also fail, as there is integration servers like the Cloud.

We simplify the concepts so that everyone can understand, of course there are many other details, but overall this is it!

Internet Dating Tips – Dating Profile Examples For Men

Let me ask you…

Are you STRUGGLING at meeting women online?

You are? Well, guess what? You aren’t alone. The fact is, MOST men fail at online dating and quit within WEEKS after posting their first online dating profile. Well, why is that? Are all women on Internet dating sites that mean? Do they just NOT like men at all?

No, obviously that isn’t the case! After all, we all know some guys that are having a LOT of success with online dating. You’ve heard about them… right?

“Dude!!! I’m getting laid left and right from women I met on Match.com. What’s your problem??? It’s so easy!”

Well, one of two things is going on there. Either these guys are lying, or they know something the rest don’t. Maybe they searched the net for dating profile examples for men, and found the “perfect dating ad.” Maybe they all look like Brad Pitt.

Well, I’m here to tell you that when it comes to having success with meeting women online, you HAVE to have TWO things right. Screw up either one of them, and you will NOT be meeting ANY women!

The first is your dating profile. This needs to be solid. It needs to really show your personality! The days of laundry lists and facts are LONG GONE! (In fact, I’m not sure these kinds of dating profiles were ever successful.) Women are drawn to EMOTIONS, and in particular mystery and intrigue.

Why do you think romance novels are so popular? Women can’t buy them up fast enough because they CAN’T resist them!

So, making your profile convey a sense of mystery is paramount and you MUST learn how to do it right. No…copying dating profile examples for men off the internet is NOT going to cut it. Women want to meet YOU, not some guy you are pretending to be.

The next thing you want to do is convey a sense of confidence. Use assertive, commanding language in your profile, BUT don’t overdo it. Confidence is sexy, cockiness is a turn off!

Finally, show some humor! Online dating should NOT be serious. Show her you have a clever sense of humor. It’s always great to end your profile by poking fun at other guys on internet dating sites.

So, now you know how to write an eye-catching, compelling online dating profile. That’s the all important FIRST step to online dating success.

How The Internet Has Developed Over The Years

Dial up internet was where it all started for the masses of people who wanted to get online in the comfort of their own homes. Computers were rarer in times gone by than they are today, when many homes may even own more than one. Dial up internet was amazing at the time, but it was also frustratingly slow. It also meant that you could not use your phone line, and if anyone wanted to call you they would find the line engaged.

Then came the next new thing – broadband internet. This promised to be much faster and more convenient, and indeed it was. Suddenly we all got our phone lines back, as the broadband service came into our homes in a different way. Now we could go back to using our phone whenever we wanted, without tying it up whenever we went online.

Broadband was definitely faster, but developments are still taking place today that have made it faster still. Fibre optic internet is the way of the future, and it is being rolled out across many parts of the country by several companies.

But it doesnt stop there. We used to be limited to using the internet when we were at home, or at another place that had an internet connection. But this has all changed because we now have mobile broadband as well. This is accessible by way of a Broadband Dongle. This unusually named item plugs into a laptop via its USB port and acts as a mobile internet connection. It means we can now go out and about with our laptops and still get online if we should need to.

Needless to say this has made a huge difference to people who work and travel a lot. A Mobile Broadband Dongle is a great way of getting online to answer emails, surf the internet and monitor our websites when we are travelling. Instead of wasting time sitting on a train or at an airport, we can use the internet via a broadband dongle and make the most of the service we get. It means we can be a lot more practical with our time, using it more than we would otherwise.

A mobile broadband dongle would have been unthinkable even a few years ago. But thanks to advances in technology we now have many more ways to connect to the internet. We can even go online via smart phones now, but we still need laptops in many different ways. If you need to have access to the internet for work, no matter where you might be, a dongle could be the answer you have been looking for.

It makes you wonder what will happen next, doesnt it?
