ASP.NET url MAX_PATH limit
asp.net, isapi, max-path, url
Solution
This is a known issue with aspnet_isapi.dll and there is currently no workaround. The reason you don't see this issue when running your site in the built-in Visual Studio Webserver (aka Cassini) is because it's all managed code and doesn't rely on aspnet_isapi.dll.
This will get addressed in a future version of ASP.NET.
Problem
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
