in thread Speeding up Apache RewriteMap script.

The mapper script only reads the file once for each VirtualHost (when Apache starts). It then sits in memory.

configuration values as assignments in httpd.conf

I'm not sure how this will solve my problem (perhaps I have not explained the problem well enough). Do you have a snippet example?

    In your OP you said "As this script is going to be hit so many times by the webserver, I wondered if anyone had ideas on speeding it up?"

    So if that is no longer perceived to be the case, I guess we can close this issue now?


    ^M Free your mind!

    Key to hats: ^I=white ^B=black ^P=yellow ^E=red ^C=green ^M=blue - see Moron's scratchpad for fuller explanation.

      Apologies for not being clear.

      Apache opens the script and holds it open for its lifetime. RewriteMap writes to it (hence the while(<STDIN>){..} loop) and waits for output from STDOUT.

      For every such mapping (read: every http request), the lookup method is called. I assumed that that is where the main speed up could be attained.

      Although I'm not sure how moot this is with merlyn's reply in play
