Query strings are can't stored in Cache storage ?

[Vasanth Mathivanan]

Hi,

We have php based applications to used for front end and back end MySQL .We have edge server to point the application server ,but it didn’t store cache that all requests are comes “TCP MISS” in log file . Then tried to enabled the plugin of cache Manipulation key (cache_key.so @@param=--include-params=true) in remap rule . It works fine but only stored “css and js ”files only .However static php file (vodservice.php) or query based file (online.php?cust_id=1637&submenu_id=120) did not stored in cache . I not sure this is correct or not ,So how to stored the php content with and without query in cache storage?

Sounds like you might also have to set it to store dynamic-looking content. I can't remember if that's the default or not...

@plugin=cachekey.so @pparam=--separator= @pparam=--static-prefix=http://replacement-fqdn.com
Is similar to what we use for a lot of our remaps and Im pretty sure that will keep the query strings, if you want them dropped you can add @pparam=--remove-all-params=true, then it will replace the fqdn with the one from the static prefix

The default is to keep all query params as long as you aren’t specifying any of the query param cachekey options

One thing to note is that separator option, which is just a blank space, without that I believe you end up with cachekeys which have elements separated by ‘/’ instead, which is fine if that’s fine with what you’re wanting

Yes , its default parameter to enabled in “proxy.config.http.cache.cache_urls_that_look_dynamic INT 1” on records.config .But its didn’t work.

I tried below given configuration using separator ,prefix etc . it seems to be problem still alive every hit goes to “MISS”

Can you send the list the header output of the various curls? eg

curl -IXGET "http://example.com/phpthatisntcaching.php"
and
curl -IXGET "http://example.com/cssthatiscaching.css"

in particular, the Cache-Control headers.

Your Cache-Control header does not allow for caching of your php --
you need to set this...
