When it was suggested to me by my sysadmin he did actually use the term "scan" - however, I'm not convinced removing the file would stop Apache looking for one. But, I could be wrong - it *has* happened before ;)
Certainly, it doesn't make sense to leave you rewrite rules in it unless you can't put them into httpd.conf for some reason (shared hosting etc). But, if that's the case then you've found the solution to your speed problems - get a dedicated server ;) On 7 Mar 2009, at 20:28, James Cauwelier wrote: > > I 've read that one before.
