1441769 - X-Moz:prefetch feature updates REQUEST_URI

Status: RESOLVED WORKSFORME

(Firefox :: Untriaged, defect)

Description

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:58.0) Gecko/20100101 Firefox/58.0
Build ID: 20180206200532

Steps to reproduce:

Unfortunately I cannot provide a link because the problem occured in a webshop, which is still in production.
In this webshop we use the X-Moz:prefetch feature on the category page.
We set the information for the next page category page in the head with the tag: <link rel="next" ....
This provides the needed information for the browser to prefetch the next page of current the category.

After loading the page the user/we add an article to the basket (by form).
After the article was added to the basket the shop redirects to the prefetched site.


Actual results:

In the process of adding an article to the basket by form we use a function to get the Request URL for the redirect after the finished process of adding an article to the basket. 
This function uses the REQUEST_URI to build the correct redirect string. 
But with the use of the X-Moz:prefetch feature the REQUEST_URI ist not the original request of the form, but the REQUEST_URI of the next, prefetched, page.


Expected results:

Despite the use of prefetch, we would expect the REQUEST_URI to be the value from original URL, not the prefetched one.

After some more hours the problem was solved.
It was not a problem concerning ff. 
The Problem was ca cookie, that was set twice (2nd time with the prefetches uri).
