url

Hi,

I've found an issue with ASP.NET that I know at least has stumped one other person out there. We were trying to use an HttpModule to handle wildcard requests to a web application. The generated url is dynamic and could potentially be several hundred characters long. Unfortunately there appears to be a limitation in the aspnet_isapi.dll file that limits the length of the path in the url to MAX_PATH which is hardcoded at 260 chars.

Has anyone else ran into this and found a way around this limit? Query string parameters are not an option.

Thanks, Greg Ballard
