[users@httpd] 503 response with mod_rewrite?
Hi all,
Is there a way to return a custom document along with a 503 Network
Unavailable response code using mod_rewrite rules? The documentation
mentions the ability to return 3xx and 4xx, but not 5xx. If 5xx codes
are unavailable - is there a specific reason why?
In case you're wondering why I would like to return a 503 code -
Google recommends returning it for 'down for maintenance' pages:

Thanks,
Evaldas

It should be possible as of httpd version 2.2 (bad documented, right)

Here's what we use. We have this at the bottom of our <VirtualHost>
sections and just uncomment and restart apache before working on the
sites.
#Uncomment to redirect temporarily while working on site
#ErrorDocument 503 /503.php
#RedirectMatch 503 ^/(?!(503\.php|503\.gif))
Not sure if that's the "right" way to do it but it works for us.

Only if you ask for it. You can turn AllowOverride on or off for any
directory. You would simply need it on for one directory. (I'm not
saying it's a good idea. I'd recommend simply changing httpd.conf and
gracefully restarting. But if you want to trigger off the existence
of a file, you might as well use .htaccess.)

If .htaccess files are enabled, Apache would check for their existance
recursively, wouldn't it? Meaning, for a requested file that is 4
directories deep it would do 5 .htaccess existence checks.

It would be no more performance-draining to check for an .htaccess
file than it would be to check for any other file as a condition for
issuing a 503.

You can't use relative paths, but you can accomplish the same thing:
RewriteRule (.*)(/[^/]*)/neuro.asp $1/neurology.php [R=301]
(That may need to be adjusted, but it should give you the idea.)

[users@httpd] 301 redirect with mod_rewrite? Possible to use relitive paths rather
then FQDN paths?
Posted by "John H. Nyhuis" <ca...@u.washington.edu>.
I was wondering if anyone has given thought to allowing the use of
relative paths with the mod_rewrite package rather then requiring full
paths. i.e., in the .htaccess file:
"Redirect 301 ./neuro.asp ../neurology.php" (does not work)
instead of:
"Redirect 301 /pedtest/divisions/neuro/neuro.asp
http://depts.washington.edu/pedtest/divisions/neurology.php"
(does work)
Just asking because our dev->testing->production setup has different
absolute FQDN's at each spot, and this means the .htaccess file is
specific to each of the environments. It would be convenient to not have
to remember to change the .htaccess file each time a new site version gets
pushed through the process.

Well, use a directory section in your httpd.conf as recommended and
described in http://httpd.apache.org/docs/trunk/howto/htaccess.html#when
(When (not) to use .htaccess files).

Unfortunatelly, that is not an option, as my site is optimized for
speed and therefore is not using .htaccess files. Upgrading to 2.2 is
not possible in short-term either.
But thanks for your suggestions guys.

Sure, just make "a certain file" an .htaccess file in the DocumentRoot
containing that directive. Otherwise, if Andre is right, you can use
all the tricks of mod_rewrite directly.

Is there a way to do this redirect on a conditional as a rewrite rule

I don't think mod_rewrite can do it. (I haven't tried it, but the
code seems to enforce 3xx on the R flag.) But it is easier with
mod_alias anyway:
Redirect 503 /
