ASP.Net web development server stop working in VS 2008

Hi folks,

One of my friends told me that he had a problem in the last couple of days, when he is trying to run asp.net web application; he was getting this error message is showing in his browser:

"Internet Explorer cannot display the webpage"

He uninstalled and installed VS 08 since he taught that this will fix the problem.

If you are facing this problem, simply do the following to fix it :

1) open the following file: "c:\windows\system32\drivers\etc\hosts"

2) Add the following entry in this file:

127.0.0.1        local host

Save the file and then try to run your asp.net application the development server will work perfect :).

Hope this helps.

Difference between clear and remove in web.config

Hi all,

I had a discussion with one of my friends about the difference between clear and remove keys in web.config, and I would like to share it with you.
Remove in web.config is to remove a specific key from the web.config, for example:
Note: <> have been replaced by {} because it is not allowed to be posted in http request.

{appSettings}
{add key="MyName" value="Mostafa1"/}
{add key="MyName" value="Mostafa2"/}
{add key="MyName1" value="Mostafa3"/}
{remove key="MyName1"/}
{/appSettings}
Remove is removing the key MyName1.
Clear is used to remove all key mentioned above it, for example:
{appSettings}
{add key="MyName" value="Mostafa1"/}
{add key="MyName" value="Mostafa2"/}
{add key="MyName1" value="Mostafa3"/}
{clear/}
{/appSettings}
I don’t recommend to use clear key in the web.config because it will cause a disaster in your application.
Hope this tip helps.
