Keeping object in cache regardless of max-age

[Mad Indian]

unless I'm misunderstanding in the vcl_fetch section you should be able to for instance if ttl is less and 2 mins make it 2 mins

if (beresp.ttl < 120s) {
set beresp.ttl = 120s;
}

or if you want to say cache any url that contains members in it for  3h

if (req.url ~ "(/members/)") {

 set beresp.ttl = 3h;
}

Anders,

Thanks for the link. This helps.

I'm going to put my vote in for this to be at least discussed at next 
months User Group meeting. I just took a look through the list archives, 
and it seems like I'm not the only one looking for this functionality :)
