Hello everybody,
while reverse proxying a page via mod_proxy_html (Apache 2.4.4) I get
wrong output charset for some parts of page. When I comment Include
conf/extra/proxy-html.conf the page is OK, but of course rewriting
internal links doesn't work. When I uncomment it, rewriting works just
OK, but charset in one button and in a posted form data is bad.
Config:
Apache 2.4.4 self compiled
Solaris 10
LoadFile /opt/csw/lib/libxml2.so
LoadModule proxy_html_module modules/mod_proxy_html.so
LoadModule xml2enc_module modules/mod_xml2enc.so
...
ProxyHTMLDoctype XHTML
ProxyRequests off
xml2EncDefault UTF-8 #or commented
ProxyPass /bohdalec/ http://10.16.133.38:20001/obj/ max=320
<Location /bohdalec>
ProxyPassReverse /
ProxyHTMLEnable On
ProxyHTMLURLMap / /bohdalec/
ProxyPassReverseCookiePath / /bohdalec/
</Location>
I have found some clues in error log that I suppose it can be the reason.
In default setup:

If I read it well, the problem is that libxml2 doesn't support neither
ISO-8859-1 or UTF-8. But according to documentation, they are always
supported and UTF-8 is the default encoding. I have tried 3 versions of
libxml2 - default Solaris version, CSW version and self compiled one. I
doubt all three versions could have such a basic problem as not
supporting default charset. Do I miss something important?
Thanks for any help
