HTTPS bug fix

Hello Stefano,

I found a bug in Hyper Cache – it affects https enabled pages on a site. We have few of these and in the hyper_cache_invalidate_post() function, the protocol type is stripped incorreclty (just substr()), so we get a wrong md5.

cache.php constructs the md5 differently.

So the cached file is never cleared when the page is saved.

As a quick fix, I changed hyper_cache_invalidate_post() to strip the protocol part of URI with a regex, rather than a set number of chars – https:// is longer than http://

$link = substr($link, 7);

was replaced with

$link = preg_replace( '~^.*?://~', '', $link );

Thanks,
Martin
