Leading and trailing slashes are + mandatory. You can also set the cookiepath to any directory which + is a parent of the Bugzilla directory (such as '/', the root + directory).

If you set this to something less + than 32, then the user will be given a checkbox for "Restrict this + login to my IP address" on the login screen, which defaults to + checked. If they leave the box checked, Bugzilla will behave the + same as it did before, requiring an exact match on their IP address + to remain logged in. If they uncheck the box, then only the left + side of their IP address (up to the number of bits you specified in + the parameter) has to match to remain logged in. + </para> + </answer> + </qandaentry> + </qandadiv> <qandadiv id="faq-security"> |
