[users@httpd] ProxyPassReverse not working as documented??? (Apache 2.2)
I simply cannot get a reverse proxy operational with mod_proxy on my Fedora
Core 6 setup (Apache 2.2). For example, if I want to proxy flickr.com (just
an example) from as http://mysite.org/flickr I should be able to do the
following according to the docs (
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#examples ):
In my http.conf for mysite.org:
<Location /flickr>
ProxyPass http://www.flickr.com
ProxyPassReverse http://www.flickr.com
</Location>
This works initially. Going to http://mysite.org/flickr sure enough gives me
the flickr main page (understand images and stuff are hosted elsewhere so
they're coming direct and not via the proxy but that's ok for our example).
But move your mouse over links like "Sign In" and other relative links and
they show as http://mysite.org/signin instead of the (required)
http://mysite.org/flickr/signin . I understand that links in the page that
start with the protocol will not be re-written but that's not my problem.
ProxyPassReverse is missing that extremely important /flickr Location
identifier for mysite.org to properly proxy this site.
This is driving me nuts and I feel that I'm missing something obvious but I
can't for the life of me get past this. Could some kind soul save me from my
frustration?
thanx,
-- Ben

Whenever possible I try to avoid modifying the URL path when reverse proxying. Then mod_proxy_html is not needed and you save some CPU cycles.
<Location /flickr>
ProxyPass http://www.flickr.com/flickr
ProxyPassReverse http://www.flickr.com/flickr
</Location>

Thanx Joshua,
I do have the mod_proxy_html going now and it works as expected. You're right about "not rewriting URL references inside html" as being pretty categorical - but we tend to see what we want to see and that following sentence implied just what I was looking for so I was perfectly capable of ignoring the prior inconvenient bit. :)

"nor will it rewrite URL references inside HTML pages", which is
pretty clear and categorical in itself.

I did read it (over and over again :) ) but it appears I was thrown off by
the very next sentence that interprets the sentence you refer to as only
applying to links in pages that contain absolute URLs which is not, as
you've clarified, what it means at all. Pardon the confusion... perhaps that
entry could be made a little more explicit?
thanx,

It seems to me you have read neither the docs for ProxyPassReverse
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxypassreverse
nor the standard tutorial
http://www.apachetutor.org/admin/reverseproxies
They'll both tell you that you need mod_proxy_html (a third-party
module) if you want links inside the html pages rewritten.
