The difference between POST and GET

25th October 2003

How important is the ability to tell the difference between data sent by POST and data sent by GET (i.e in the query string) when developing web applications? Some web frameworks (such as PHP) provide separate mechanisms for accessing POST and GET data. Others (such as Python’s cgi module) provide a single interface to form information that doesn’t distinguish between the two. I already have a strong opinion on this but I’m going to leave it open for discussion here for a bit before weighing in.
