unknown directive "if" in /usr/local/nginx/nginx.conf

[Mark Maunder]

Igor,

Does the 'if' statement in mod_rewrite have any trouble working with 
external modules that are compiled in? I'm seeing that variables used in 
external modules are not being set if they're inside an 'if' block. See 
my previous message about 12 hours ago with subject "Module vars set 
inside if's are not set" for details.

Mark.

The if statement below is just a test to validate the if statements work.  As you can see, I get the "unkown directive" error.  Do you think I need to use the --with-pcre= option?
