HTTP

The Hypertext Transfer Protocol (HTTP, http) is the basic, underlying, application-level protocol used to facilitate the transmission of data to and from Web server. HTTP provides a simple, fast way to specify the interaction between client and server. The protocol actually defines how a client must ask for data from the server and how the server returns it. HTTP does not specify how data actually transferred; this is up to lower-level network protocols such as TCP.
The first version of HTTP, known as version 0.9, was used as early as 1990. HTTP version 1.0 as defined by RFC 1945, is supported by most servers and clients (Web browsers). However, HTTP 1.0 does not properly handle the effects of hierarchical proxies and caching, or provide features to facilitate virtual hosts. More important HTTP 1.0 has significant performance problems due to the opening and closing of many connections for a single Web page.
The current version HTTP 1.1 solves many of the past problems of the protocol. It is supported by version 4-generation Web browsers and up. There still many limitations to HTTP however, it is used increasingly in applications that need more sophisticated features, including distributed authoring, collaboration, multimedia support, and remote procedure calls. Various ideas to extend HTTP have been discussed and generic Extension Framework for HTTP has been introduced by the W3C Already, some facilities such as client capability detection and privacy negotiation between browser and server have implemented on top of HTTP, but most of these protocols are still being worked out. For now, HTTP continues to be fairly simple, so this discussion will focus on HTTP 1.0 and 1.1.

Problems with URLs

Problems with URLs

The primary problem with URLs is that they define location rather than meaning. In other words, URLs specify where something is located on the Web, not what it is or what it’s about. This might not seem to be a big deal, but it is. This issue becomes obvious when the problems with URLs are enumerated;

URLs aren’t persistent. Documents move around, servers change names, and documents might eventually be deleted. This is the nature of the Web, and the reason why the 404 Not Found message is so common. When users hit a broken link, they might be at a loss to determine what happened to the document and how to locate its new home. Wouldn’t it be nice, if no matter what happened, a unique identifier indicated where to get a copy of the information?

URLs are often long and confusing. People often have to transcribe addresses. For example, the following is quite a lot to type, read to someone, or avoid not breaking across lines in an email;
http://www.democompany.com/about/press/presidentail.cfm?id=7&view=screen

Firms are already scrambling for short domain names and paths to improve the typability of URLs, and most folks tend to omit the protocol when discussing things. Despite these minor clean-ups, many URLs are very long and “dirty,” filled with all sort of special characters.

URLs create an artificial bottleneck and extreme reliance on DNS services by specifying location rather than meaning. For example, the text of the HTML 4.01 specification is useful document and certainly has an address at the W3C Web site. But does it live in other places on the Internet? It probably is minored in a variety of locations, but what happens if the W3C server is unreachable, or DNS services fail to resolve the host? In this case, the resource is unreachable. URLs create a point source for information. Rather than trying to find a particular document, wherever it might be on the Internet, Web users try to go to a particular location. Rather than talking about where something is, Web users should try and talk about what that something is.

How long this last?

“Crisis on wall street, or with the world”

Crisis on wall street, or possibly the next depression from eighty years ago. Greed is the main problem on Wall Street, we all knew it would effect everyone. The Banks, are all crashing to Bankruptcy. The million dollar birthday parties, and the hundred dollar burger. People taking advantage over the stock market and the CEO positions. Too much money causes greed, now who needs a 3 thousand dollar hair cut and a 3 million dollar birthday party when everyone is heading for the next depression…its called greed !!!

How long will it last? How long did the last depression last? Because of all those big spenders, and high rollers we all suffer…do you remember the movie about the poor switches positions with the rich? This may happen. I don’t think that we all realize that we maybe, or actually … we should conserve. How will we even trust the Banks if they crash, and where are we at when it comes to jobs, money, and global warnings? Where do we place our money where we think it will be save.

Do you think the political party suffers from any depression and from the Banks closing? They never suffer from any of these money problems and yet they speak like they are concerned. They haven’t a clue what it like to struggle, yet they say that they are going to help us with the economy.
In the news yesterday, I heard that even Google may not pay everyone because of this crisis. It took me over a year to earn 75 dollars and now they put another hold on my account to verify my email and address. This is the second time they have done this to me, how many times must I verify my email, and address?
