W3 Total Cache
Wrong Last-Modified headers / Twitterfeed (5 posts)

    Apparently my server/wordpress install is not sending the apropriate Last-Modified headers and twitterfeed.com can't see that our blog is updated.

    This site is on bluehost using W3 Total Cache.

    Thanks for any insight or past experience with this!

    Have you tried it with W3 Total Cache (and other plugins) disabled? If so, does that make a difference? You may want to try a different caching plugin temporarily too, such as Quick Cache or WP Super Cache.

    The last modified header is not controlled by W3TC, it sets headers like expires, etag, cache-control etc.

    I can see in PgCache.php, there is one code block which sets the Last-Modified header. Ideally it has to be the modified date of the post, page etc.

    Code Block:
    $headers = array_merge($headers, array(
    'Last-Modified' => w3_http_date($time),
    'Vary' => 'Cookie'

    What are your browser cache settings?
