But I need to do it: **ok I try to explain better my situation**:
- I've got a class that is a "javascript repository". Its role is to respond with a string of javascript functions. Javascript functions are organized in indipendent modules (list of functions), so I can attach to my page just needed functions. Different modules can share same functions. - In my view I specify the url of a function (it is in the same view), get_js_code, whose rule is to return javascript code (with: `return HttpResponse(code,content_type="application/x-javascript")` ) - get_js_code initiate that "javascript repository class", asking one or more modules (list of functions), and my class returns functions just one time, even if a function belongs to more than one module. - in my template I specify get_js_code url as a javascript resource, and javascript code is downloaded with the page from Django It works well _BUT_: - a module is needed from every app, so I specify in a Middleware an url that brings to another app/function that initiate that class in order to attach as javascript resource the common javascript module. **Here is the problem**: - my "javascript repository class" has a list that contains returned javascript functions list in order to return a function just one time. It works well but just one time: infact if I reload the page the list does not expire and no javascript funtions are returned. Very hard to explain, I hope its clear now. PS: I was wrong, I don't initiate the class inside a Middleware. PPS: I know that is unusual to put javascript code inside Python code, but I'm testing this solution.
