You can tell if mod_perl is in use by the setting of the
MOD_PERL
environment variable. There are other things about the environment an admin really needs to be able to find out when TWiki is live, so I propose this:
ENV{"varname"} -- inspect the value of an environment variable
Returns the current value of the environment variable
varname
. For security reasons, only those variables listed in
{AccessibleENV}
in the
Security Settings/Miscellaneous section of
configure
can be displayed. Any other variable will just be shown as the emtpy string, irrespective of its real value.
If a variable is not set (as against being set to the empty string) it will be returned as
not set
.
Also took the opportunity to move the HTTP_HOST, REMOTE_* env var eccessors into TWiki variables for deprecation.
