[users@httpd] mod_proxy_html how to stop code fixing
I have configured Apache Apache/2.2.3 on CentOS 5.5 as a reverse proxy
using mod_proxy_html, and both Apache and mod_proxy_html are working
correctly. The problem is that I am trying to access a Promise storage
Array which has horrible html. Specifically, MULTIPLE </html> tags in the
same page:
... the first half of the page ...
</script>
</body>
</html>
<html>
<head>
<title>Promise WebPAM PROe</title>
... the remaining part of the page.
If I enable page re-writing with SetOutputFilter proxy-html, then
mod_proxy_html stops re-writing when it encounters the first </html> tag.
If I do not enable re-writing, the first page is displayed on the Firefox
client, but subsequent links are in the form http://192.168.x.x/whatever
instead of URL/alias/whatever.
Is there a way to stop mod_proxy_html from trying to fix the html while
still re-writing the URLs?

Thank you, Nick, for your rapid and obviously knowledgeable advice. I will try the solutions you suggest and report back to the group with results in case someone else is having a similar problem.

I've seen this problem before. The basic problem is obviously your backend's
non-HTML. It's not actually mod_proxy_html fixing it, but the underlying parser
(libxml2).
I've some recollection of working around this for a client, but that was some years
ago and I couldn't tell you how - unless perhaps you can trick the parser using
mod_xml2enc's xml2StartParse to squish the first <html> (I'd have to try it to see
how the parser responds to that). But that's an outside chance: otherwise you're
probably better off with a plain text search-and-replace like mod_sed,
mod_substitute or mod_line_edit.
