APPLIES TO
- Microsoft ASP.NET 1.1
- Microsoft .NET Framework 1.1
SYMPTOMS
The 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.
CAUSE
A 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.
