Title is pretty much self explanatory...
I want to find a particular match but with condition.
I will give an example so it would be more clear:
http://www.example.com//test.htm
https://www.example.com/test.htm
https://www.example.com///test.htm
ftp://www.example.com//myFile.jpg
I want to find all // but except the the http://
so iow...
if there is a :
character (http://) before the //
ignore it...
return only matches that do not have :
before //
