[users@httpd] POST encoding

[Computa Computa <cc...@yahoo.fr>]

Hi

I use Apache httpd and mod_rewrite as a reverse proxy between an IIS and end-users. When filling forms, strings sent from the browser to the proxy via a POST transaction are not encoded the same way compared to the strings sent directly from the browser to IIS. Here is an example bellow. As one can see, the string "téléphone" is encoded "t%E9l%E9phone" when sent to IIS and "t%C3%A9l%C3%A9phone" when sent to the Apache proxy. To my knowlegde, %E9 is a normal UTF-8 encoding for é, but I don't understand the encoding used by Apache nor does it works well with the Web application (it displays strange symbols). I thought it might be a content negociation problem and I set the parameters "DefaultLanguage fr" and "AddDefaultCharset Off". I also have all the AddLanguage and AddCharset. Anyone has an idea of what could be wrong ?

Thanks a lot,

Matthieu
