The request URL is invalid in IIS 7

here is my URL

http://abc.domain.com/controller/action/A74444C3A7FA858C7995CA9954CBCF1E26604634767C5575396D908E8415CF8CCC04C05F49FED0AA9D9743B69ABF232BDE9787A5222D081DA638896C0D2379A673E1747A2FFE1158F14AF098B2899D2ABEB4EA738D89369627E479796B6B2B9EA9B247CC59EF10E3A88B6A56A87F0818E2AD2A942FFA31F1C941BB7AF6FDC55FE6733353F28DFAC1827688604CBFBAB4856E6C75F810D13923F9D913F51F5B02980163E6CD63BC04610AD2C12E07360D7BC2C69F1B0CD03E

There are no invalid characters in the URL itself as everything is encrypted. Still I am getting

Bad Request - Invalid URL HTTP Error 400. The request URL is invalid.

I know the URL is awfully long and I was able to resolve that issue in my Cassini by adding this httpRuntime maxUrlLength="512"

in the web.config

However in IIS7 even after playing around with the requestfiltering maxurl and maxquerystring values I have not been able to resolve this.

This is an asp.net mvc 3 application.

Solution

  • Your problem is you're not using a query string, but a path. A path has a maximum length of 255.
