Item306: PublicCacheAddOn: pcad gives Error 500

On behalf of Raymond Lutz on 25 Nov 2008 :

I'm having some difficulty getting this one off the ground. Installed it every way possible. In all cases, it can't run pcad?clear. Here is the result of the install:

[copswiki@rpdz2 twpc]$ ./install -q -O -v /home/copswiki/www/twiki/bin
Installing twnc
Compiling pccr.c
Warning: could not clear cache by calling http://www.copswiki.org/twiki/bin/pcad?clear
Check that the binurl= line is correctly defined in /home/copswiki/www/twiki/bin/pc-config
Install Ok. FYI admin page is at http://www.copswiki.org/twiki/bin/pcad
[copswiki@rpdz2 twpc]$ cat /home/copswiki/www/twiki/bin/pc-config
TWPC_VERSION='4.6'
bin='/twiki/bin'
binurl='http://www.copswiki.org/twiki/bin'
...

Which is correct. When I just try to run pcad from the command line, I get a blank response.

There are no hints in error logs, etc.

Trying to access pcad from the browser gives 500 error.

If there is an Error 500, there should be some message in the apache logs. Could you look for it?

I suspect what is described in http://twiki.org/cgi-bin/view/Plugins/PublicCacheAddOn#Use_with_perl_accelerators

Sorry about my delay. At this point, I am going to be working to get the Page Caching facility that is included in the 1.1.2 release of foswiki working. Thus far, it is not stable enough to rely on, but I will take that up elsewhere. I am therefore closing this item.
