Introduction to HTTP mind-map

Sunday, March 1st, 2009

As I promised about 4 hours ago, here is my introduction to Hyper Text Transfer Protocol in form of a mind map.
It is to be intended as a really short introduction to this protocol. Like the previous one about computer networks, the mindmap summarizes materials copyrighted by Tanenbaum and also material taken from Wikipedia.

The topics covered are:

  • Scope of the protocol
  • HTTP connection
    • HTTP/1.0
    • HTTP/1.1
  • HTTP request methods:
    • GET
    • HEAD
    • PUT
    • POST
    • DELETE
    • TRACE
    • CONNECT
    • OPTIONS
  • Message Headers
    • Request Headers - all
    • Response Headers - all
  • Status Codes:
    • 1xx Information
    • 2xx Success
    • 3xx Redirection
    • 4xx Client error
    • 5xx Server Error
  • Sessions:
    • Cookies
    • Server-Side sessions
  • Secure HTTP - HTTPS:
    • By URI scheme
    • HTTP Upgrade Header
    • SSL/TLS

As always, you are free and encouraged to contact me in case of errors or anything else.
Hope you like it!

New domain: from daniel.graziotin.net to bd-things.net

Sunday, September 21st, 2008

As I previously announced, I purchased a brand new domain for my stuff.
The blog is changing during the months, becoming more than a blog but less than a site.
That's because I decided to buy the domain BD-things.net, because this site contains all of my things, files, thoughts, projects, publications.
The old address daniel.graziotin.net now redirects permanently here and every link should have been updated/rewritten. Please contact me if you encounter problems.
I also took BD-blog.net which points here, too, but I won't renew it the next year.
Some things are different now, but you won't notice it ;)
I obviously lost my decent position at Netcraft's Most Visited Web Sites rank list, but I don't care. It will be funny to advance with the new domain and reach a even better position!
I hope there will be a new beginning and a brand new life with BD-things!

VERSIONE IN ITALIANO
Dear Msn buddy, I'm going to change account.
For technical and political reasons I won't continue to either use Microsoft Window Live Messenger or its protocol MSN Messenger.
I'm going to use Jabber/XMPP.
I would like to keep in touch with you and my other 200 contacts, so I decided to (more...)
