RE: pragma no-cache HTML only with beresp.http.Pragma ?

Hi,
Varnish deals with HTTP headers, not HTML content. The meta tags tell your browser not to cache the page, but if the web server does not add the corresponding HTTP headers in its response, varnish will have no clue about what to do, and will apply the default TTL.
Regards,
Thierry

Objet : pragma no-cache HTML only with beresp.http.Pragma ?
Greetings,
I would like take in consideration the cache information from a HTML
page only, example this :
<html>
<head>
<meta http-equiv="Cache-Control" content="no-cache" />
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="0" />
</head>
<body>
Hello world !
</body>
</html>
And this is a part of my default.vcl (only a debug part) :
sub vcl_fetch
{
if ( beresp.http.Pragma ~ "no-cache" )
{
set beresp.http.X-Cacheable = "found no-cache !";
return(hit_for_pass);
}
But it's don't work, it seem Varnish see only a header information (sent
by PHP exemple), but nothing from a HTML page only.
Do you have an idea to take in consideration the HTML <head> with
Varnish 3.0 please ?
Thanks so much,
Elodie.
