. However, it takes a regular expression as an argument instead of a simple string. For example: <LocationMatch "/(extra|special)/data"> would match URLs that contained the substring "/extra/data" or "/special/data". See also: How Directory, Location and Files sections work for an explanation of how these different sections are combined when a request is received -------------------------------------------------------------------------------- LockFile directive Syntax: LockFile filename Default: LockFile logs/accept.lock Context: server config Status: core The LockFile directive sets the path to the lockfile used when Apache is compiled with either USE_FCNTL_SERIALIZED_ACCEPT or USE_FLOCK_SERIALIZED_ACCEPT. This directive should normally be left at its default value. The main reason for changing it is if the logs directory is NFS mounted, since the lockfile must be stored on a local disk. The PID of the main server process is automatically appended to the filename. SECURITY: It is best to avoid putting this file in a world writable directory such as /var/tmp because someone could create a denial of service attack and prevent the server from starting by creating a lockfile with the same name as the one the server will try to create. -------------------------------------------------------------------------------- LogLevel directive Syntax: LogLevel level Default: LogLevel error Context: server config, virtual host Status: core Compatibility: LogLevel is only available in 1.3 or later. LogLevel adjusts the verbosity of the messages recorded in the error logs (see ErrorLog directive). The following levels are available, in order of decreasing significance: Level Description Example emerg Emergencies - system is unusable. "Child cannot open lock file. Exiting" alert Action must be taken immediately. "getpwuid: couldnt determine user name from uid" crit Critical Conditions. "socket: Failed to get a socket, exiting child" error Error conditions. "Premature end of script headers" warn Warning conditions. "child process 1234 did not exit, sending another SIGHUP" notice Normal but significant condition. "httpd: caught SIGBUS, attempting to dump core in ..." info Informational. "Server seems busy, (you may need to increase StartServers, or Min/MaxSpareServers)..." debug Debug-level messages "Opening config file ..." When a particular level is specified, messages from all other levels of higher significance will be reported as well. E.g., when LogLevel info is specified, then messages with log levels of notice and warn will also be posted. Using a level of at least crit is recommended. -------------------------------------------------------------------------------- MaxClients directive Syntax: MaxClients number Default: MaxClients 256 Context: server config Status: core The MaxClients directive sets the limit on the number of simultaneous requests that can be supported; not more than this number of child server processes will be created. To configure more than 256 clients, you must edit the HARD_SERVER_LIMIT entry in httpd.h and recompile. Any connection attempts over the MaxClients limit will normally be queued, up to a number based on the ListenBacklog directive. Once a child process is freed at the end of a different request, the connection will then be serviced. -------------------------------------------------------------------------------- MaxKeepAliveRequests directive Syntax: MaxKeepAliveRequests number Default: MaxKeepAliveRequests 100 Context: server config Status: core Compatibility: Only available in Apache 1.2 and later. The MaxKeepAliveRequests directive limits the number of requests allowed per connection when KeepAlive is on. If it is set to "0", unlimited requests will be allowed. We recommend that this setting be kept to a high value for maximum server performance. --------------------------------------------------------------------------------
