There is no way to implement a complex regex to page rules and bring down the count of page rules. There should be a way to a smart way to select page rules , something like for a workflow . Lets take an example , suppose I have a url
And these are url/expressions for me -
Now I should have a capability to have a single rule for www.example.com and inside the rule a way to define workflow to define the way I want to cache the above urls. In that I will be able to remove all the clutter of the page rules and avoid maybe repeating a same page url.
