SharePoint 2010: HTTP Request to external resources

If you have tried to create a web or a http request to an external resource using asp.net or SharePoint (for example in a webpart or a timerjob) you might get a nice error message like this:

“The remote name could not be resolved”

So if you are running your request with the host account or network service account and trying to request an external resource like google api or other web applications inside your company, you might not get the proxy settings.

Option I

A good explanation can be found here written by Rick Strahl.

He suggests to add the following to the web.config file of your application:

<configuration >
<system.net>
<defaultProxy>
<proxy bypassonlocal=”true” usesystemdefault=”false” />
</defaultProxy>
</system.net>
</configuration>

This disables the automatic use of the proxy. For more information please look also at this support article from Microsoft.

Option II

There is still another option which might work as well. Please look into the proxy settings of the Internet Explorer and check if they are configured right.

This solution worked for me fine.
