RewriteCond to compare file sizes

[mohammad aghanabi <m.websoft@xxxxxxxxx>]

Hello

4 years ago a user offered [https://bz.apache.org/bugzilla/show_bug.cgi?id=43845] a modification to mod_rewrite.c which would made it usable to compare file sizes within RewriteCond CondPattern. 

and someone commented on it "trunk has support for complex expressions in RewriteCond which also offer file size comparison"

I want to know what happened to that suggestion, applied or not and if not what that comment is about?

Thanks
