I've been experiencing some problems with ExpiresActive and external js files. ExpiresActive is set to 1 second, which works great with windows 98 and 2000. However, not that well with XP - it returns js errors, causing the script not to load properly. I've tried to change it from 1 sec to 10 min, but that doesn't help. I believe it might have something to do with the XP Security Package (SP) 1. Has anyone else encountered similiar problems and if yes, did you find any solution to it?
