URL Hash
Hi everybody!
I have a big problem, I'm using TS as reverse proxy and i'm trying to cache a simple web site.
Everything is working fine but when the user is logged in the site. In that moment the nickname should be shown at top of the page but it doesn't happen because the url has been cached priorly with the same url.
For example:
- www.example.com/cart is cached without any user logged in. Then a user is logged in the site the page shown is the first one (the page within user logged in) instead the page with the nickname at top.
My question, It is posible to cache two different version to the same url depending if a cookie in present or not??.
Thank in advance.
Jorge

I was thinking to use lua in the following way:
1) lua remap: if cookie is there the plugin rewrite url into " http://nocache.com"
2) remap.config: map http://nocache.com http://www.mysite.com
3) cache.config: dest_domain=nocache.com action=never-cache
Can something like that be a possible solution?

WP is sending one cookie from the plugin Mobile Website Detector (websitez_mobile_detector), besides other cookies are sent from the server like google analytics cookies (__utma, __utmb …).
Really when the user is logged in the site the wordpress_logged_in_e1b30b5b176d5cfe63955c27f6f1d510 is create in this case.
I would like to serve one version of site to all anonimous user from cache and when the worpress_logged_in cookie is present serve one no cache version.
Is not a problem of WP of course, this problem is extending to any web page with private zone.
Any idea?

I could have sworn Wordpress took care of this by default, by making sure
that "personalize" content is not cacheable. Cc:ing Kurt Payne (not sure if

You can use the lua plugin to alter the configuration for specific requests.

Maybe you could detect the cookie, then alter the request configuration and set a Vary header to generate the alternate hash?

It's documented in the file, but to be explicit
You want to edit the etc/trafficserver/cache.config file.
You can set up a URL match with either dest_domain or url_regex. You might want dest_domain in your situation. With each match you can control some of the cache parameters, including whether cookie responses are cached. So
dest_domain=www.example_domain.com prefix=cart action=ignore-server-no-cache cache-responses-to-cookies=0
Unfortunately you must have a cache action in addition to the cookie parameter, so you'll have to pick one.

You can do something similar with the cache.config file. With that you can match URLs by regex and then tweak the cache_responses_to_cookies value just those URLs with the "cache-responses-to-cookies" option.

Could it be posible to do that i want with LUA plugin???

Hi Alex,
I have proxy.config.http.cache.cache_responses_to_cookie configured to 1, I mean to cache all content although the cookie is present.
If I set that param to 3, the html is not cached and all html content go back to the origin servera, so it is not valid for me.
As you say, the site send a cookie when the user is logged (wp_loggin) in but the problem is when there is not user logged in, other types of cookies are sent too.
I'm using a Wordpress as a backend server and I can modify the code.
In varnish you can create a different hash if an determinare object is present or not (like a cookie in this case).
Thanks!

Hi Jorge,
I think you must have some cookies set when the user is logged id, to identify the session.
By default ATS is not caching Cookie header.
In that case you need to enable cookie header to be cached and not skipped in records.config.
proxy.config.http.cache.cache_responses_to_cookies 1;
Or see documentation of this parameter:
Set this variable to specify how Traffic Server caches cookied content:
0 = Do not cache any responses to cookies.
1 = Cache all responses to cookies.
2 = Cache responses to cookies of image type only.
3 = Cache all responses to cookies except text content-types (the default)..
I hope it will resolve your issue.
Regards,
Alex
