Great thanks,<br><br>got one more question If I do this it caches everything, it never gets to the else return(pass), the reason I have the if set that way is I want it to cache the home page but if the client clicks on anything else once they get to home page, not to cache and send the cookie. <br>
<br>Thanks again.<br><br>:<br><br>sub vcl_recv {<br>if (req.url ~ "/"){<br> unset req.http.cookie;<br> return(lookup);<br>}<br><br>else {<br> return(pass);<br>}<br><br>
}<br>sub vcl_fetch {<br> if (req.url ~ "/"){<br> set beresp.ttl = 300s;<br> set beresp.http.cache-control = "public, max-age = 300";<br> set beresp.http.X-CacheReason = "varnishcache";<br>
unset beresp.http.set-cookie;<br> return(deliver);<br> }<br>}<br><br><br><br><br><br><div class="gmail_quote">On Fri, Feb 11, 2011 at 9:29 AM, Caunter, Stefan <span dir="ltr"><<a href="mailto:scaunter@topscms.com">scaunter@topscms.com</a>></span> wrote:<br>
