Subject Re: [users@httpd] mod_rewrite problem
Date Thu, 08 Mar 2007 17:20:47 GMT
Just got a response from the developer of the PHP script  
(serendipity). Turns out the problem lies there, and not with the  
rewrite rule. Apparently what's going on is that the php script uses  
the REQUEST_URI to determine what to display. If it doesn't recognize  
the REQUEST_URI (as is the case with /nagios) it just displays the  
main page. It would appear that while mod_rewrite successfully  
rewrites the URL and calls the PHP script, it doesn't actually change  
the REQUEST_URI, so the script is still acting on /nagios, which it  
doesn't recognize. I'll admit this is somewhat beyond me at the  
moment, perhaps I need to look more into the difference between the  
REQUEST_URI that the php script is seeing and what, exactly,  
mod_rewrite is changing. At any rate, that at least explains the

yeah, sorry. That was one of the things I was experimenting with.  
Since I knew the later rewrite rule worked as intended, I thought I'd  
try just rewriting /nagios into what the second rule was designed to  
match. Kind of a kludgy grasping at straws solution that didn't help  
anyway. The line that I am actually running is back with the  
index.php? section, I just copied and pasted the wrong code block.

Interesting point. However, as these rules were added by serendipity  
and not me, and don't affect anything anyway, I'm not too concerned :)

yep :) Actually, the original rule set did have a blanket  
anything.html => index.php?url=$1 rule, but as that made it so I  
couldn't access the non-serendipity directories on my server (trying,  
for example,, which is an  
actual page, just wound up back at the home page), I removed it.  
Thinking about it though, a more elegant solution might be to put  
that rewrite rule back in by itself, and then use a RewriteEngine Off  
directive in my other directories to override it, or some such  
solution. It bears consideration.

well, it WOULD have the same effect, but for some reason Options  
Indexes is the default for the / directory, so if I don't override it  
for my other directories it generates an index page if you request a  
directory without an index file, which I don't want. I suppose a  
better option would be to simply remove the Options Indexes from the  
root level Directory block :)

which does appear to be the case, as per the developer response.  
Thanks for the thoughts!
