For details on the availability of Windows binaries see:
1. No provision was made for operating systems with a very low limit on the
number of separate data blocks that could be passed to system
call. This was an issue on Solaris where the limit is 16 and meant that since

--service-log option to
specifying the name of a log file for a specific service script. The
arguments are the name of the service and the file name for the log. The

mod_wsgi-express to identify
that it is being used, what hosts it is handling requests for, and whether
debug mode and/or specific debug mode features are enabled. This is so that

MOD_WSGI_EXPRESS - Indicates that
mod_wsgi-expressis being used.
MOD_WSGI_SERVER_NAME - The primary server host name for the site.
MOD_WSGI_SERVER_ALIASES - Secondary host names the site is known by.
MOD_WSGI_RELOADER_ENABLED - Indicates if source code reloading enabled.
MOD_WSGI_DEBUG_MODE - Indicates if debug mode has been enabled.
MOD_WSGI_DEBUGGER_ENABLED - Indicates pdb debugger has been enabled.
MOD_WSGI_COVERAGE_ENABLED - Indicates if coverage analysis has been enabled.
MOD_WSGI_PROFILER_ENABLED - Indicates if code profiling has been enabled.
MOD_WSGI_RECORDER_ENABLED - Indicates if request/response recording enabled.
MOD_WSGI_GDB_ENABLED - Indicates if gdb process crash debugging enabled.
For any environment variable indicating a feature has been enabled, it will be set when enabled and have the value ‘true’.
For the list of server aliases, it will be a space separated list of host names.
