WEBLOGMAX xxxx — Max cached logins held for a single user
WEBLOGMAX is a parameter on JANUS DEFINE, which defines and sets characteristics of a Janus port.
This parameter indicates the maximum number of cached login sessions to be held for a single user. This parameter has no effect unless the WEBLOGHOLD parameter is set to something other than 0.
Since a single web page can contain many images, and since browsers often request images on a page in parallel, a single request for such a logon protected page can result in multiple simultaneous logons for the userid. Logon caching would then hold these logons, tying up several sdaemons in the process. WEBLOGMAX would prevent more than the indicated number of sdaemons to be used for a single user's requests. All login protected requests for a user are then threaded trough WEBLOGMAX users. This is generally not a problem since the typical bottleneck for most requests is network bandwidth, and multi-threading requests for a single user does not alleviate network bandwidth problems. For more discussion of the logon caching feature, see Janus Web Server login caching.
WEBLM is a synonym for WEBLOGMAX.
Valid only for WEBSERV ports.
