asp.net development server port not same as web application port

Question

When i run my asp.net web application on VS2008 SP1, it starts ASP.NET development server with port 1257 but web application is trying to be browsed on localhost:1559. So my web application can not be browsed by the explorer because the url is incorrect. I have to change the url manually on the explorer's address bar to browse web my application. You can guess this is a bit annoying.
How can i resolve this issue? (1257 and 1559 are just examples.)

Answer 1

I answer my own question incase someone needs the solution.
The problem is about ESET antivirus program which i have. In ESET settings you need to go through "settings/advanced settings/Web access security/Web browsers". Then you will see a list of processes which ESET accept as a web browser. Uncheck the checkbox of "C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\devenv.exe" or "C:\Program Files\Microsoft Visual Studio 9\Common7\IDE\devenv.exe".
Then ESET will stop scanning your asp.net development server and your port number will match with the port number of opening browser page url.
