Bad Request (400): Why?

Question

Why do I get a 400 - bad request error using the following URL? It is encoded using Server.UrlEncode. The actual path query parameter is C:\Development\Chase\Exports\ChaseExport-090312073930.zip

http://localhost:50199/Common/Forms/Export_Stream.aspx%3fpath%3dC%3a%5CDevelopment%5CChase%5CExports%5CChaseExport-090312073930.zip

Answer 1

You should not urlencode the entire querystring, just the values, so URL should be

http://localhost:50199/Common/Forms/Export_Stream.aspx?path=C%3a%5CDevelopment%5CChase%5CExports%5CChaseExport-090312073930.zip

Answer 2

Try this:

http://localhost:50199/Common/Forms/Export_Stream.aspx?path=C%3a%5CDevelopment%5CChase%5CExports%5CChaseExport-090312073930.zip

Answer 3

I've written an article with Stefan's help that explains how to do this:
