There are some strange variations that I'd like to understand what they are made for.
I couldn't find out there in the researches I did, so I came here as my last resource.
This is the list of things I'd like to understand:
https://ssl.google-analytics.com/r/__utm.gifand the second one calls
https://ssl.google-analytics.com/__utm.gif. So what's the difference between the /r/__utm.gif and /__utm.gif?
I'm asking all this because I believe some of those variations might be making the second URL to not work in the end. Given the second URL is not producing entries (pageviews) in the GA admin pages.
I discovered the root cause of my problem. The cause wasn't lying in the code.
The problem was that marketing team is using a View Filter with specific "Include" rules. And the page that wasn't getting in the statistics wasn't also included in that rule.
I'm not very familiar with all the features Google Analytics provides, so beware about these filter capabilities to avoid spending so much time in a silly thing like I did. :P
