Difference in method POST and XPOST

Hi All,

What is the difference b/w writing method and X before method for e.g

PUT and XPUT
GET and XGET
POST and XPOST
DELETE and XDELETE
HEAD and XHEAD

Please share the link if any to understand

If you use curl you need to use -X, if you use Sense you don't.

Ok Mark, Thanks for making it to understand diff.
