[users@httpd] Re-use of a Setenv directive
Hi
I have defined a SetEnv Directive this way:
SetEnv BASE_PATH /tmp/smthg
I would like to re-use this variable in another SetEnv Directive, e.g.:
SetEnv PATHS $BASE_PATH/a:$BASE_PATH/b:$BASE_PATH/c:...
But $BASE_PATH is not interpreted as a variable.
I tried with quotes, back-splash, ...
How can I re-use this variable in another SetEnv Directive ?
Thanks
Apache 2.2.3, Linux kernel 2.6.18, x86_64

RE: [users@httpd] Apache 2.2.3 > mod_disk_cache not caching if a DirectoryIndex is used
Posted by Geoff Millikan <gm...@t1shopper.com>.
This issue impacts all index.html, index.php, index.shtml, etc files even
the "homepage." For example:
This is cached: http://www.mycompany.com/index.php
This *is not* cached: http://www.mycompany.com/

[users@httpd] Apache 2.2.3 > mod_disk_cache not caching if a DirectoryIndex is used
Posted by Geoff Millikan <gm...@t1shopper.com>.
Is this a known bug?
At URL #1 below the content isn't cached (or served out of cache):
http://www.t1shopper.com/mod_disk_cache_bug/
At URL #2, we just add the "index.php" into the URL string and the cache is
working properly (see log below).
http://www.t1shopper.com/mod_disk_cache_bug/index.php
Am I missing something?
Thanks,

Re: [users@httpd] Re-use of a Setenv directive
Posted by Sébastien Moretti <se...@unil.ch>.
Hello Dave,
thanks for your help.
In fact, I just want to define BASE_PATH in order to re-use it in PATHS.
PATHS contains several times BASE_PATH and I would like to change
BASE_PATH value once instead of several times in PATHS.

http://httpd.apache.org/docs/2.2/configuring.html#syntax
> Also, what's mod_define?
That's a module that lets your define variables inside Apache
configuration. They are resolved with the same syntax ${XXX}. The
difference to the shell environment variables is, that
- you can redefine (change config) and do (graceful) restart.
This won't work for shell variables, because all children are still
forked from the same original parent process, which hasn't changes its
environment
- you can use the features of the normal config files (include etc) and
define the variables closer to were you use them.
mod_define was part of the 1.3 mod_ssl written by Ralf Engelschall. I
ported it to 2.x and offered to include into trunk some time ago. At
least Stefan Fritsch liked the idea :)
One minor problem: The ${xxx} syntax clashes with RewriteMap syntax.
You can find the port at
http://people.apache.org/~rjung/mod_define/
Feedback welcome.

Rainer

Nope. That's in 2.2 -- it's (heavily) (ab)used by Distros like
Debian and their like.
Also, what's mod_define?

Is this post-Apache 2.2.x functionality, or are you talking about
mod_define to get this functionality?

It does exactly what I want.
But I cannot do it automatically if apache is started automatically at
boot time. Except if I add this in /etc/init.d/httpd2 script but will
have to re-do it each time apache is updated.

You should be able to do this via:
- Use a RewriteCond to match against the BASE_PATH variable
- Use a RewriteRuke with an ENV= flag to set PATHS using the back
reference to the matched variable
Clumsy, but should work.
If the values are in fact static, i.e. do not depend in the request,
virtual host etc., you can actually use the fact, that Apache allows you
to resolve unix environment variables (not the same as Apache
environment variables) inside the Apache configuration. The syntax is
${VARNAME} (do not drop the curly braces).
- Set env var outside of Apache before starting:
BASE_PATH=/var/smthg
export BASE_PATH
Use variable inside Apache config:
SetEnv PATHS ${BASE_PATH}/a:${BASE_PATH}/b:${BASE_PATH}/c:...
or
<Directory ${BASE_PATH}/somesubdir>
etc.
