We are using varnish 4.1.2 for our website caching. We use bunch of
standard query parameters (like utm*) to track the channels for our
website visits - this is quite standard in the web world.
Can I 'ignore' query string variables before pulling matching objects
from the cache, but not actually remove them from the URL to the end-user?
For example, all the marketing|utm_source|,|utm_campaign|,|utm_*|values
don't change the content of the page, they just vary a lot from campaign
to campaign and are used by all of our client-side tracking.
So this also means that the URL can't change on the client side, but it
should somehow be 'normalized' in the cache.
Essentially I want all of these...
... to all access HIT the cache for|http://example.com/page/|
However, this URL would cause a MISS (because the param is not a utm_*
Would trigger the cache for
Also, keeping in mind that the URL the user sees must remain the same, I
can't redirect to something without params or any kind of solution like
Would appreciate if you could help me with the above to increase the
performance of our site.
