A few ideas/comments:
1. Are you sure it's Apache doing the caching? Browsers tend to be very aggressive cachers. Beating the #$%^ out of Ctrl-F5 (or whatever your browser uses) seems to be a necessary evil.
2. Make sure mod_cache is excluded from your Apache config (I presume you have control over your dev machine.)
3. What language are you writing your cgi's in? It may be possible to set a switch so Apache launches your interpreter/app in debug/single-step mode. Have a wander round the Apache howto's, starting
here[
^]
4. Lots more thing are possible in Apache, like setting cache control headers to tell the browser not to cache responses. (see 1 above.)
Chew on this lot and comment if you feel inspired.
Cheers,
