Hi all,
This is my first post to the apache list -- please bear with me,
though I'll try to do this the right way.
Our team is new to Apache. We have a SharePoint 2007 app that sits on
our internal server, at an address we'll call
http://internal.site.com.
We are required to use Apache as a reverse proxy from the
external-facing site to the internal server. the external server is at
an address we'll call http://external.site.com/appname.
The issue comes with SharePoint's relative links. links in the
sharepoint page might point to "/_layouts/dir/subdir/page.aspx" but
when passed through to the proxy, this link shows in the page as
http://external.site.com/_layouts/... (no /appname appended on). So it
seems we have to do a URL re-write.
But then this is extended to other issues -- relative URLs in
stylesheets, javascript, etc. that SharePoint generates (i.e. we have
no control over).
SharePoint also creates some URLs along the lines of
"\u002flayouts\u002fuserdisp.aspx?Force=True\u0026ID="
So far, I think the best way to address this is, for each URL
(including in stylesheets, javascript, etc.):
1. Switch the incorrectly-facing slashes.
2. Turn any relative URLs (URLs beginning with "/" is how i'm assuming
we can define this") and turn them into
http://external.site.com/appname/[URL]";
3. Use ProxyPass and ProxyPass reverse to transform the paths (which
should all now be absolute and correctly formatted).
This may be right or wrong and I welcome your opinions on how to do it better.
In pursuit of that goal, so far I've got a config file that I'm
certain is wrong in many ways, but I think is a start. I'd like your
opinions on how to better implement my idea as well.
