[users@httpd] ProxyPass with parameters
Hi,
I am using 2.0.48 and it works pretty fine. Now I would like to use
ProxyPass to include content from a third party source (yes I do have the
permission to include the information). The thing is that ProxyPass seems to
have problems with including content from a external source if the URL does
contain parameters? So I have tried using ProxyPass like this:
ProxyPass / http://www.example.com/?userid=xyz-123
Unfortunately I get a 404 not found from the external source when I access my
server saying that /?userid=xyz-123 could not be found. But when I enter the
URL above in my browser it works pretty fine. What might be the reason for
this and how can I solve it?
Bye and thanks,
Werner.

There is no reason to use ProxyPass. It is designed only to handle the
simple case. Your case is not simple.
Since you haven't showed us any details, it is hard to tell what your
problem is. If I had to guess, I would say that you need something closer
to
RewriteRule ^/(.*) http://example.com/$1?whatever
so that you don't send all the requests to the same page.
See the mod_rewrite docs for more details.

Hi,
a loop is created although the third party system is a non-local one.
Hhm, I change it back to the ProxyPass thing. Did anyone ever used ProxyPass
with parameters? I mean is this a bug or why does Apache escape the
parameters (like ?userid=xyz-123)?
Bye and thanks,
Werner.

That's what I just showed you.

Well, you need to do a little more analysis. Check the access logs and
see what kind of requests apache is processing. Are you sure you didn't
create a loop by proxying back to the same server?

Hi,
is there a way to prevent Apache from escaping the parameters?
I have now add the following lines to my httpd.conf:
RewriteEngine On
RewriteRule / http://www.example.com/?userid=xyz-123 [P]
Now when I restart the server the loads gets very high and the child processes
die:
[Thu Nov 20 01:03:22 2003] [error] server reached MaxClients setting, consider
raising the MaxClients setting
[Thu Nov 20 01:03:53 2003] [warn] child process 15378 still did not exit,
sending a SIGTERM
[Thu Nov 20 01:03:53 2003] [warn] child process 15381 still did not exit,
sending a SIGTERM
[Thu Nov 20 01:03:53 2003] [warn] child process 15383 still did not exit,
sending a SIGTERM
[Thu Nov 20 01:03:53 2003] [warn] child process 15400 still did not exit,
sending a SIGTERM
[Thu Nov 20 01:03:53 2003] [warn] child process 15412 still did not exit,
sending a SIGTERM
[Thu Nov 20 01:03:53 2003] [warn] child process 15413 still did not exit,
sending a SIGTERM
Did anyone ever experience this problem? Do you think this is a bug?
Any other idea how I could include content from a remote third party using
Apache directives (except of ProxyPass which seems to escape parameters!)?
Bye,
Werner.

Apache is probably escaping the ?.
Try this:
RewriteEngine On
RewriteRule / http://www.example.com/?userid=xyz-123 [P]
