ModProxyPerlHtml.pm  view on Meta::CPAN

In some conditions javascript code can be replaced by error, for example:

        imgUp.src = '/images/' + varPath + '/' + 'up.png';

will be rewritten like this:

        imgUp.src = '/URL/images/' + varPath + '/URL/' + 'up.png';

To avoid the second replacement, write your JS code like that:

        imgUp.src = '/images/' + varPath + unescape('%2F') + 'up.png';

ModProxyPerlHTML replacement is activated on certain HTTP Content Type. If you
experienced that replacement is not activated for your file type, you can use the
ProxyHTMLContentType configuration directive to redefined the HTTP Content Type
that should be parsed by ModProxyPerlHTML. The default value is the following
Perl regular expresssion:

	PerlAddVar ProxyHTMLContentType    (text\/javascript|text\/html|text\/css|text\/xml|application\/.*javascript|application\/.*xml)

If you know exactly what you are doing by editing this regexp fill free to add
