Hi all! I have such problem with IIS 6.0 configuration. I have a web site with HttpHandler inherited class which catch all requests. When I publish this site on IIS 6.0 and try to launch this application by entering "http://mydomain.com/test-www;par@act=value&Parameter=mypar" my site doesn't catch this request and IIS returns Bad Request (400) error May be RFC 1738 Url Standard works here and IIS can't obtain such requests. But may be there is a way to solve this problem Thank you very much in advance -- modified at 4:42 Thursday 29th November, 2007
