[SaF] where to learn about URLs?

[dguevel]

Hi,

I would like to know where to obtain a tutorial or reference that could
help interpret URLs.

e.g. (faked) : what does this URL implies? a javascript, cgi, etc.?


http://www.book.com.ar/bookshow/mostrarlib.exe?lpcur|001|0|0|bookshow

Is these an archive in html or a database?
