Is there any specific route map/pathway to follow to develop a web-framework and topics and things to learn, pre-requisites?

I'm about to develop a simple web-framework based on python for my Final Year Project. I am googling about this stuff and not getting information about a specific route map/path way that drive/guide me i.e. pre-requisites, topics to learn to be able to develop a framework for example, 1st step is to learn about browser that how browser works, 2nd step is to learn about url, how it works. Some stuff is available on internet but they are much more older. Kindly give me a specific route map so that I can build this easily because I have to make this in about 5 months.
