Good catch! Seems like it was mod_evasive which was causing the problems - had been installed by a colleague to secure against DoS attacks, but inevitably gives problems with legitimate traffic trying to make simultaneous requests. Explains exactly both why it was so erratic in behaviour & why I couldn't see other people having these problems! /me crawls into a hole in shame... Many thanks for your help - makes a world of difference :) Fran. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
