Hi,
Can anyone advise of the order in which <Proxy> statements matching the
same URL are matched?
I am using SetEnvIf to set a variable that is saved later in the
access_log. Sometimes there is a more specific match and a less
specific match for the same URL, e.g.:
<Proxy http://server1.example.com/*>
SetEnvIf Server_Addr . VAR=first
Allow from all
</Proxy>
<Proxy http://*.example.com/*>
SetEnvIf Server_Addr . VAR=second
Allow from all
</Proxy>
My observation is that the matches are done in reverse order of
appearance in the configuration, i.e. in this example, a request to
http://server.example.com/ will match the http://*.example.com/* rule
and the variable will be set to "second". Is it generally correct that
matches are in reverse order of appearance in the configuration?
I don't know the details of how <Proxy> sections work, but there is an
alternate possible explanation to what you are seeing :
*both* sections above are run, in the order in which they appear,
because both of them match.
So the first SetEnvIf is executed (VAR=first), but the second one
overwrites it (VAR=second).
I believe in this case you may want to use some RewriteCond/RewriteRule
(mod_rewrite) to do what you want.
