IIS max request url limit?

The .Net Framework has a restriction of MAX_PATH (260) characters on physical path and so asp.net has a similar restriction on urls.

FYI http://forums.iis.net/t/1105360.aspx

 

For ASP.NET 4.0. :

 

Add settings to config file
<httpRuntime maxRequestPathLength="260" maxQueryStringLength="2048" />

For Earlier ASP>NET version

 

In the registery 'HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters', add following entry

"UrlSegmentMaxLength"=dword:00000200 (512 characters) and I restarted system for the registry entry to take effect.
