Are slashes allowed in URL fragment or query?

Question

My understanding of the general form of a URL is that it looks as follows:

://?#
         


        

Answer 1

Fragment can contain any character at all.

Query can contain any character except for #, as it is treated as marker (but you can use URL-encoding to still have it there)

So, in general, there are no any reserved characters as long as there is no ambiguity.

See RFC 3987 for the most up-to-date info. Your "general form" is not exactly right
