Improved caching of web server templates ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Template Toolkit processors used by Apache are now cached for better performance (by virtue of thereby being able to take advantage of Template Toolkit's internal caching mechanism). In addition, the *compiled* versions of the templates themselves can be cached to provide an additional performance boost. Two Apache virtualhost configuration variables are added to control caching of compiled templates: * `OILSWebCompiledTemplateCache` - specifies location on the web server filesystem to store compiled templates. * `OILSWebTemplateStatTTL` - specifies number of seconds before checking to see if a newer version of a cached template is available. As a result of the caching changes, it is now necessary for Evergreen administrators to reload Apache to ensure that a change to (say) TPAC templates becomes visible.
