[users@httpd] Re: Conditional response body modification
I've come up with the below config using mod_ext_filter which isn't
desirable, but it's the only thing I've been able to come up with so far.
It's not working exactly yet. Any suggestions?
SetEnvIf HTTP_COOKIE "USER_TYPE=test" FILTER=$1
*Inside VirtualHost:*
ExtFilterDefine doug mode=output intype=text/html enableenv=FILTER \
cmd="/bin/bash /apps/httpd/scripts/replace.sh"
<Location />
SetOutputFilter doug
</Location>
*replace.sh*
#!/bin/bash
/bin/sed -r 's/http\:\/\//https\:\/\//g'

I really wish I could go to 2.4, but we're stuck with 2.2 due to using
Adobe and Oracle modules that don't support 2.4 yet. I feel like I'm
really close to coming up with something using mod_parp, but just
can't figure how to use it exactly. Documentation is clear up until I
get to the API section and that looks like I need good knowledge of
programming to understand.

In 2.4, it seems like you should be able to register mod_substitute
via mod_filter. mod_filter has a "match" parameter that in 2.4 is an
ap_expr expression, so it can ready basically anything floating around
in the server.
mod_filter can be pretty intimidating though.

I wasn't able to come up with anything further on the mod_ext_filter
solution. I did come across mod_parp <http://parp.sourceforge.net> (
http://parp.sourceforge.net). It says it's able to parse the request data
and make it available to other apache modules. I've gotten it compiled and
enabled on my apache, but I'm not sure I'm understanding how to pull the
data into mod_substitute. Anyone have any ideas how I can make the
HTTP_COOKIE data available to mod_substitute? Let me know if I'm
completely off base here in understanding what this module can do as well.
Thanks
<IfModule mod_parp.c>
SetEnvIf HTTP_COOKIE "(^|)CUST_TYPE=test" parp
</IfModule>
