HTTP 400:在 URL 中检测到无效字符.IIS解码URL太早?这里发生了什么? [英] HTTP 400 : detected invalid characters in the URL. IIS decoding URL too early? Whats going on here?

问题描述

So i have this URL: http://test.com/afolder/who-else-wants-to-make-horror-movies%3f/

which is URL encoded version of : http://test.com/afolder/who-else-wants-to-make-horror-movies?/

But IIS7 throws a 400:

HTTP Error 400.0 - Bad Request ASP.NET detected invalid characters in the URL.

But why is it doing that if i have correctly encoded the URL?

I'm also having the same issue with other URL encoded chars like '/' which is '%2f' but when .net resolves the handler it does so after decoding the URL which then changes the effective path, grrrr.

解决方案

Looks like there are some issues with IIS7 on x64....not sure if this is your issue or not:
