IPC::Cache and how to clear the cache

Hi all, I'm not sure if this is an appropriate place to ask. I've looked over the "Guide" and couldn't really determine for sure how to do this. I am using the IPC::Cache module to store some configuration information in shared memory for mod_perl modules that I've written. The problem I'm faci

Weird log file entry related to use of constant

Based on the examples in "Writing Apache Modules with Perl and C" I'm trying out the use of constants in a CGI program for Apache::Registry. At the moment the program is only running under Apache::PerlRun The problem is its filling up my log file with non-fatal, but space consuming message.

RE: Embperl struggles

The LOG filehandle is predefined by Embperl. Anything written to it is put into Embperl's log file (usually /tmp/embperl.log). If you use a different name, you will probably be OK. On the other hand, you can just delete the call to "open" (and "close) and use the log file Embperl already provi
