PerlSetVar to empty

[André Warnier <aw...@ice-sa.com>]

Hi.

Ref :
Apache/2.2.3 (Debian) DAV/2 SVN/1.4.2 mod_jk/1.2.18 PHP/4.4.4-8+etch4 
mod_ssl/2.2.3 OpenSSL/0.9.8c mod_perl/2.0.2 Perl/v5.8.8 configured -- 
resuming normal operations


This is a really silly question.
I have a configuration where at the global server level, I set

PerlSetVar myvar "somevalue"

, but in a a specific <Location>, I would like to reset this to

PerlSetVar myvar ""

However, when I do this, I get the following error restarting Apache

Starting web server (apache2)...Syntax error on line 196 of 
/etc/apache2/sites-enabled/ska:
PerlSetVar takes two arguments, PerlSetVar
  failed!

Anybody know how I can do this ?
is there a PerlUnsetVar myvar ??
or a PerlSetVar myvar undef  ??

Note :

PerlSetvar myvar " "  (one space)

works, but then it makes the test inside the module rather ugly.

I've never done this, but did you try undef?  Or maybe 0, if you just
want to test for true.
