FIX: A Content-Type header that is incorrectly formatted causes the QueryString part of the URL to be decoded incorrectly in ASP.NET (841451)
The information in this article applies to:
- Microsoft ASP.NET (included with the .NET Framework 1.1)
- Microsoft .NET Framework 1.1
SYMPTOMSThe Microsoft ASP.NET Request.Url property and the Request.QueryString.Get method do not return correct data for a URL.
The QueryString bytes are decoded as a Unicode string when they really are a UTF-8 string. Therefore, every two characters or two bytes are replaced with one Unicode character in the URL.CAUSEA Content-Type header that is incorrectly formatted causes the QueryString part of a URL to be decoded incorrectly in ASP.NET. Specifically, this problem occurs when a Content-Type header does not end with a pair of quotation marks.RESOLUTIONA supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article.
