Subject: [htdig3-dev] HTDIG_CONFIG_FILE env variables
From: Chuck O'Donnell (cao@bus.net)
Date: Mon Nov 20 2000 - 05:50:40 PST
I'm new to the list and I'm not sure if this has been previously
discussed. We have patched the release version of htdig (htdig-3.1.5)
to allow for environment variables specifying default config files and
directories under different Apache virtual domains. In our httpd.conf,
we use something like this:
<VirtualHost customer.domain>
ServerName www.customer.domain
ServerAdmin webmaster@customer.domain
DocumentRoot /m/domain/customer.domain/htdocs/
Alias /stats /m/domain/customer.domain/stats
SetEnv HTDIG_CONFIG_DIR "/m/domain/customer.domain/etc/htdig"
SetEnv HTDIG_CONFIG_FILE "/m/domain/customer.domain/etc/htdig/htdig.conf"
</VirtualHost>
This allows us to maintain different databases for each document tree,
and the customer doesn't have to remember to put
<input type=hidden name=config value="...">
in the search form.
Below is the patch we use against the release sources. I would be
happy to supply a patch against current if anyone is interested. It
would be nice to have a feature like this enabled without having to
patch the sources on future installations.
Thanks all,
Chuck
