[Plugin: WP Super Cache] Accepted Filenames & Rejected URIs

I want to say “all files which PERMALINK contains letter h”

More precise: it adds
<!-- Page not cached by WP Super Cache. No closing HTML tag. Check your theme. -->
To the end of every file like myPaper.pdf, myProgram.cpp and others which people can download from my site. I added

.h
.zip
.pdf

to the list of forbidden URIs for caching, but now all pages which contain letter ‘h’ in their name are not cached too ??

I have solved the problem: these strings are regular expressions. So, the dot symbol matches any char!

So, the default values (like “wp-.*.php”) are incorrect: it should be “wp-.*\.php”. This was the first bug in WP-Super-Cache.

The second bug was in the source code that prevented from entering backslashes in the list.

The correct rejected URIs are:

wp-.*\.php
\.(?!php)

The correct allowed URIs are:

wp-comments-popup\.php
wp-links-opml\.php
wp-locations\.php

Thanks this whas very helpfull.
