rewrite rules problem

Draco

I moved a site to a new server recently and for some reason my rewrite rules are acting slightly differently.

On the original server, the url in the location bar and the request_uri stays the same (which I want)
On the new server, the url changes to the url the rule redirects to.

They're both running apache 1.3.31. I can't see any differences in their configurations. any pointers?

rewrite rule on old server:

RewriteRule     ^(.+)$  [url]http://defttest.eeng.may.ie/~draco/main/common/this_file.php?module_id=12[/url]

rewrite rule on new server:

RewriteRule     ^(.+)$  [url]http://wopr.eeng.may.ie/main/common/this_file.php?module_id=12[/url]

isn't it because the directory paths are different on the servers?

Draco,

1) You don't seem to be pulling the content in parentheses into anything in the RewriteRules? There's no point in parenthesising if you're not going to backreference; it's a waste of the processor.

2) The behaviour on server 1 is absolutely correct, mod_rewrite won't force a redirect unless you pass an [R] flag to it. With this in mind, I'm guessing it's the tilde (~) and paths causing the problem. Have a think about that and I'll come back to it tomorrow, you know, when I'm sober?

1) I was orginally using a backreference so that's why they're there. Gone now.

2) My problem is with server two. It is doing the unwanted redirect. I moved stuff around on server one to get rid of the ~ and it's still working as wanted, so it's not that.

It's hard to tell from afar to be honest, but it's likely to be a slight difference in environment on the new server. I'd suggest setting up a RewriteLog with the RewriteLog and RewriteLogLevel directives and examining that. If you can't figure it out immediately, set the RewriteLogLevel to 9, call the URL a couple of times, and post the output here.

got it this morning. The second server thought it had to do a REDIRECT/302 as the server name was set just to wopr rather than wopr.eeng.may.ie.

Bah. I knew it was something stupid I had missed.

Still unusual though, since mod_rewrite is such a low-lying module it usually takes precedence over everything else (Redirect, Alias, etc). Anyway, glad you figured it out.
