RE: [PBML] 3 Great Mysteries of Perl (to me)
- I'm pretty sure that POST and GET are equally as insecure as easch other.
I mean, unless you're using SSL, you could snoop all the info right off
the wire anyway :-)
POST allows for slightly stingier web servers to be a little more
pedantic, by only passing URLs of a certain length. This is all my buggy
memory, so YMMV, as usual.

What you have described is the GET method.
The POST method allows more information to be
sent. It uses an HTTP transaction to transfer
data. I think(?) it POST is also more secure than
GET. The RFC allows both methods to be used
simultaneously. In a html form you can specify
GET or POST in the method element. CGI.pm
defaults to POST.
RFC's are maintained at: http://www.rfc-editor.org/

Semi-colons and ampersands can be used
interchangeably. I think(?) the semi-colon was
introduced in HTTP 1.1 and that HTTP 0.9 and
1.0 used the ampersand.
