Varnish¶

Given you have this Setup:

Varnish -> TYPO3

SOLR Indexer might have some issues, when the page to index is behind a Varnish Proxy. We have collected two ways of solving this issue

Bypassing varnish¶

Bypass when X-Tx-Solr-Iq is present¶

The SOLR indexer request send the header X-Tx-Solr-Iq.

To have bypass the Varnish caching, but this into your sub vcl_recv part of the configuration

    if (req.http.X-Tx-Solr-Iq) {
        return(pipe);
    }

Using Cache-Control¶

Put this into your sub vcl_fetch part of the configuration

    if (req.http.Cache-Control ~ "no-cache") {
        set beresp.ttl = 0s;
        #Make sure ESI includes are processed!
        esi;
        set beresp.http.X-Cacheable = "NO:force-reload";
        #Make sure that We remove alle cache headers, so the Browser does not cache it for us!
        remove beresp.http.Cache-Control;
        remove beresp.http.Expires;
        remove beresp.http.Last-Modified;
        remove beresp.http.ETag;
        remove beresp.http.Pragma;

          return (deliver);
    }
