Hello,
I am obviously a new nginx user, so please bear with me.
I have setup nginx as a content caching service, running on port 80 and
directing traffic to backend servers.
all works okay, though one specific scenario where i want to cache an object
matching a specific query string.
Here's a sample:
.../ getimage.view&id=19823&class=5617&size=80
I want to cache objecting matching : class=5617&size=80
since obviously the ID will change depending on user.
i googled nginx config,etc... everything i found simply explains that i could
match $uri and $args but not how to bypass args
i tried the following:
if ($uri ~* "^getimage.view") {
set $args $2$3;
set $cache_key $scheme$host$uri$is_args$args;
}
But it's not working....
any advice? or better yet any place i can learn more about manipulating query
strings ?
Thanks in advance.
