Using Drupal 7.19 and Views 3.5 cache is not respecting contextual filter argument- it is displaying the same cache result no matter what argument given. How to get this working properly?
This is a Views bug actually and it is not solved yet, but you can work around it by using this patch if you are using contextual filter Taxonomy with depth as I guess, and if it didn't work you can turn off the "Field Language" for the view if you have neutral language content, but this patch is not complete as there is some issues not solve, you can see the full discussion of this issue here issue here
Fixed since 7.x-3.8
