Apache reverse Proxy charset problem

[webfuture]

I have setup a proxy on FC3 with apache... Here's the relevent info in httpd.conf

ProxyPass /intranet/

http://10.1.1.23/

ProxyHTMLURLMap

http://10.1.1.23

/intranet

<Location /intranet/>
ProxyPassReverse /
SetOutputFilter proxy-html
ProxyHTMLURLMap / /intranet/
ProxyHTMLURLMap /intranet /intranet
RequestHeader unset Accept-Encoding
ProxyHTMLExtended On
</Location>

I have those error message in apache error log.

Unsupported charset Windows-1252 in HTML META
No usable charset information: using old HTTP default LATIN1

So from what I understand, the html re-writer mod_proxy_html need to understand the charset coming from the proxied web server. This particular one is using a windows charset that apache on linux does not understand and this is giving a parsing error and the proxy of that server fails.

Any ideas of what I can do?
Is there a way to make apache understand the charset Windows-1252?

Thanks

I contacted the developer of mod_proxy_html.

Here's his response.

What matters here is whether libxml2 understands the charset, since it's libxml2 that converts. It's not down to apache or linux.

If you *know* your input is a particular charset like Windows-1252, the solution would be to convert it before it reaches the proxy.
If the backend were Apache, then mod_charset_lite there would do the job. You might still get messages in the log, but the pages will display correctly through the proxy.

Anyway, isn't windows-1252 mostly identical to iso-8859-1?

Hope this help someone...
