New in Apache HTTP Server 2.4 – Authorization, FCGI Proxy, and Mod_SSL

The authorization container directives <RequireAll>, <RequireAny> and <RequireNone> may be combined with each other and with the Require directive to express complex authorization logic.

The example below expresses the following authorization logic. In order to access the resource, the user must either be the superadmin user, or belong to both the admins group and the Administrators LDAP group and either belong to the sales group or have the LDAP dept attribute sales. Furthermore, in order to access the resource, the user must not belong to either the temps group or the LDAP group Temporary Employees.

The following Apache HTTPD directives are for controlling processes launched by Apache children. Raising the maximum resource limit requires that the server is running as root, or in the initial startup phase. They apply to processes forked off from Apache children servicing requests, not the Apache children themselves. This includes CGI scripts and SSI exec… Read More Control Apache CPU, Memory, and Processes with httpd.conf

PHP Caching and Acceleration with XCache

Up until today, I was still using eAccelerator on all of my servers. However, a post on the vBulletin.com forums prompted me to give XCache, the new PHP accelerator from the maker of lighttpd, a try. I’ve got to say, while I’ve only been using it for about 6 hours at this point, it blows eAccelerator out of the water, especially once you enable multiple caches (which benefits SMP systems).… Read More PHP Caching and Acceleration with XCache
