RE: [users@httpd] ProxyHTMLURLMap issues ... resent .. surely somebody can help with this
I think the reason no-one has replied is that no-one knows...
You are using a 3rd party module that many people will be unfamiliar with (eg, me) so it's not too surprising no-one feels able to respond. I did look up the module's homepage and noticed that the author offers to try to help out registered (ie, paying) users - is it worth £50?
Rgds,

Subject: [users@httpd] ProxyHTMLURLMap issues ... resent .. surely somebody can help with this
Hi,
Please help ... been grinding away for days :-).
I am trying to reverse proxy to my internal web site from the outside.
The internal web site has CSS and Java and everything.
HOWEVER.
The internal web site uses a "CSS Hack" (??) to get around browser issues in IE.
When I browse the internal site directly I see this in the source.
<!--[if lt IE 7.0]>
<script src="/javascript/iepng.js"></script>
<![endif]-->
<!--[if lt IE 7.0]>
<link rel="stylesheet" href="/css/ie6fix.css" type="text/css"/>
<![endif]-->
<!--[if IE 7.0]>
<link rel="stylesheet" href="/css/ie7.css" type="text/css"/>
<![endif]-->
When I view the page source via the proxy.. this piece of the code is MISSING, and the apache log shows this
Non-HTML content; not inserting proxy-html filter, referer: http://intranet.fff.xxxxdu/tv/
I am presuming this is related to the error.
The displayed page is missing its "theme", which I am assuming is to do with the "hack"
How can I get ProxyHTMLMap to pass this content through.
Config snippet is
# ------- TV
# To support scripting events (with ProxyHTMLExtended On),
# you'll need to declare them too.
ProxyHTMLEvents onclick ondblclick onmousedown onmouseup \
onmouseover onmousemove onmouseout onkeypress \
onkeydown onkeyup onfocus onblur onload \
onunload onsubmit onreset onselect onchange
ProxyHTMLLogVerbose on
LogLevel debug
ProxyHTMLExtended On
ProxyPass /tv/ http://tv-3:8088/
ProxyHTMLURLMap http://tv-3:8088/ /tv
<Location /tv/>
ProxyPassreverse /
SetOutputFilter proxy-html
ProxyHTMLURLMap / /tv/
ProxyHTMLURLMap /tv /tv
RequestHeader unset Accept-Encoding
</Location>
</VirtualHost>
Thanks
peter

The second parameter in the log message is the level that the message was
logged at. Maybe there is another LogLevel directive somewhere that is
overriding what you think is being set.

Yep .. according to the doc.. this is the safest way to do a reverse proxy.
Sometimes the thing proxies properly .. usually the first time .. and then
a refresh give me a web site (the proxied one) unavailable.
If course it is working now ... even with the errors in the log..
but I am the only user on at the moment

Another thing, nothing to do with your original question, but which
puzzles me :
In your config, you seem to be "proxying away" links with "/weather/",
yet right after that you have a <Location /weather>. Is this Location
section then ever used at all ?

Maybe just because you set the log level to "debug" ?
They do not look like error messages.

Lol!
I read your previous reply the way you wrote it, and had to figure this one out!

Good idea.
p.s. to the OP, what happens if you run your HTML through xmllint --html?
If the "comment" disappears, it's too broken for libxml2. If the comment
survives xmllint but gets eaten by mod_proxy_html, then I should be
investigating and hopefully fixing something!

Come to think of it, that was a somewhat-legitimate feature request.
Maybe I'll add it to a future 3.2 release.
Meanwhile you might find it easier to revert to a non-markup-aware
filter such as mod_sed, and work your way through any "false
positives" that arise out of context-blind pattern matching.

Very likely true, though I'd add I don't think I've seen the post

mod_proxy_html won't rewrite comments. It'll pass them through
untouched or strip them out - no other option.

That's a non-HTML document (as determined by the Content-Type header),
not a comment in an HTML document.
