The HTTP/1.1 protocol is the current way most browsers request and send information over the web (i.e. how your browser speaks to an internet web page, in simple terms). The browser first makes a connection and sends a request to get a page. Then as that information is returned, it can contain additional resources needed (images, CSS, scripts) that are then requested.
Browser (or client) — your web browser, be it Opera, Firefox, Internet Explorer or something else.
Server — the program that manages the remote web site you visit.
Connections — think of it as a line of communication opened up between browser and server.
Persistent Connection — a connection between the browser and a web server that stays open to allow more than one element to pass between them (saves on the time and resources invested in opening new connections). Used by default in Opera, with the settings defined in Preferences » Network. RFC2616 specifies that only a maximum of 2 persistent connections should be established between the browser and server. Opera sets half of the "max connections per server" to be persistent connections and half to close for performance reasons{1}{2}. Often too many connections to a server are far less efficient than a smaller number that are pipelined and persistent. Opera developers suggest a maximum of about 8 connections per server{1}.
Pipelining — allowing more than one request from the browser to be sent before receiving a reply from the server (the server MUST always return them in the same order they were sent). This often reduces the page loading times (especially on high latency connections like dial-up and on cache validation), and especially reduces the numbers of packets needed for a page (re)load {3}. Opera pipelines by default - and uses heuristics to control the level of pipelining employed depending on the server Opera is connected to{1}. In Firefox, pipelining is OFF by default and needs to be turned on (see about:config[1]), Firefox also uses some heuristics, especially to turn pipelining OFF for IIS servers. IE doesn't pipeline at all.
[1] Here are my Firefox Network settings:
user_pref("network.http.max-connections", 32);
user_pref("network.http.max-connections-per-server", 8);
user_pref("network.http.max-persistent-connections-per-server", 4);
user_pref("network.http.max-persistent-connections-per-proxy", 32);
user_pref("network.http.pipelining", true);
user_pref("network.http.pipelining.firstrequest", false);
user_pref("network.http.pipelining.maxrequests", 4);
user_pref("network.http.proxy.pipelining", true);

I have learned sreeval things in the Network Marketing industry. I can PROMISE you why people FAIL.There are only really a handful of great opportunities out there from a COMPANY standpoint.Here are a few keys to AVOID failure when deciding to join a network marketing company.1.You need to have a STRONG WHY to do this business. It is not for the people who are not sure of WHO they are.2.Examine the product and or service being offered and decide if it makes sense to YOU.3.Make sure you have strong LEADERSHIP within the company.4.Your DIRECT SPONSOR needs to be a LEADER in your company or at least DEPENDABLE enough to point you to one that is in your up-line that will make a COMMITMENT to your FUTURE SUCCESS.5.You need to become a LEADER or you must have a good relationship with a LEADER in your circle.6.People follow people with whom they KNOW,LIKE and TRUST. Can YOU be trusted and can you trust OTHERS?7.Your MIND-SET must be on the level of what you will see on my MIND-SET tab. Be sure to take a look.8. Personal Development of yourself and your TEAM,must be of UTMOST importance to you.9. Learn the compensation plan and work in harmony with that to get promoted as well as be COACH-ABLE and learn from your leadership.10. Many people feel because they make a great deal of money at their J.O.B.,they can just come into this sort of business and do it without TRAINING, that is not so. The people who get PAID the best in this business are the ones that FOCUS on it as a BUSINESS ,non-traditional as it may be, it is business nonetheless.11. Remember this FACT Hobbies COST you money, but BUSINESS MAKES you money! 12. We only generally have 40yrs of our lives to get this right! Choose WISELY and LEVERAGE your time and effort, its the ONLY way to secure your FUTURE! Working a J.O.B. will NEVER give you such an OPTION.These are all the REASONS why I created this site. To EMPOWER the powerless and to TEACH the HUNGRY how to eat financially in this NEW economy and to give HOPE to the depressed! We can do so much MORE than what we have done thus far. I CHALLENGE you, LOOK back on your past and ask yourself, what GIFTS do you have that you have let your FEAR stop you from helping others and changing the course of your family's FUTURE? Think about it .TOGETHER WE STAND,DIVIDED WE FALL! JOIN ME become one of the FEW,the proud, THE WORLD WIDE WINNERS of TOMORROW! God Bless You and be very careful who you let advise you, because if you take someone's advice, you also accept their LIFESTYLE.. If you run with 5 BROKE friends, you will end up the 6th!If you are ready to start on a path to a wealthy future, submit an email to me on my page.

That's not true; pipelining can be enabled through the registry.
