I've been looking through my logs, and for fun, I'd like to let the spiders know the content is new, and was only published, say, 2 minutes before the spider got there. :) And I'd like to let caching servers know they shouldn't hold my stuff, so that I can get a better read on traffic. This should increase the bandwidth I'm using, but be much more fun to read in the log files.
I've read through some of the apache mod_headers documentation at apache.org, but I'm still a little confused. I tried a couple things, and they gave me a 500 error after I tried accessing the site with the new .htaccess file in place.
Does anyone here have some experience playing with mod_headers? I think the command in the file should be ExpiresActive On
after that, though, what I found was a little hard to follow. still not very technical ;)
