Accessing File Modified Date in .htaccess

Question

Is it possible to get access to file attributes such as when a file was created or last modified?

I have cached gzip files, and would like to be able to set a last-modified header to them. Something like:

<If CLIENT CAN HANDLE GZIP && IN DIRECTORY CACHE/HTML/>
    Header Set Last-Modified {WHEN-FILE-WAS-LAST-MODIFIED}
</If>

Or is there some other way of doing this?

"Or is there some other way of doing this?" Depends, what do you need it for? Basically what is the purpose? – Allaallah

I have gzipped files of raw HTML pages - a cache to save my server creating these pages for each request. I'd like to be able to send a Last-Modified header with these gzipped HTML files. I know this could be done with PHP, but I'd rather avoid that. – Ellanellard
