I wouldn't mind using that, except that it does not work for me... (i
have copied a part of the original message below as that got snipped...)
I have a situation where it is convinent for me to define a global
"PerlSetVar" in my httpd.conf and then unset it for particular virtual
hosts.
I used to use the following configuration successfully:
----------------------------------------------------
httpd.conf
----------
<Perl>
use Apache::Server;
Apache->server->dir_config->unset("MyVar");
</Perl>
-----------------------------------------------------
That stopped working for me ever since we compiled
Apache/1.3.26 (Linix - Debian) with mod_perl/1.27
Has anyone else had the same issue?
On a similar note:
The following pices of code do not work:
-----------------------------------------------------
code sample 1
--------------
1. sub handler {
2. my $r = instance Apache::Request(shift);
3.
4. $r->dir_config(MyVar => undef);
5.
6. $r->dir_config->unset("MyVar");
7.
8. $r->dir_config->set(MyVar => undef);
9.
10. }
None of lines 4, 6 or 8 actually unset the variable.
A collegue tells me that if a "true" value (for the key MyVar) is not
passed to set then it ends up returning the value of MyVar - but then
how i want to set the value of MyVar to be false. I would have though
that unset/set would have specifically done what i told them to
unset/set rather than do fancy things with truth values...
