What is the difference between a search engine and meta search engine?
A meta-search engine is a search tool that sends user requests to several other search engines and/or databases and aggregates the results into a single list or displays them according to their source. Metasearch engines enable users to enter search criteria once and access several search engines simultaneously.

A "callback URL" is the web address an API needs to send information for use in a different web site.
For example, a web developer is building a web application for use in conjunction with another web service's API (such as Facebook or Last.fm). The application is hosted on the web developer's server, and the other web service stores the callback URL so that it knows where to send information when it is requested by the developer's application.

What are the advantages and disadvantages of having cookies on a web page?
Without cookiesEvery time someone visits the site, they are asked which layout they want to use. People are discouraged from visiting as they have to answer this question every time they load up your site.
With cookiesThe first time the site is loaded, visitors are asked which layout they want. After that, it is automatically displayed every time they visit the site.
2. Remember login detailsAnswers.com always remembers your login name. How? It uses cookies that identify you to their server. Other sites use cookies for this too. Google, Facebook, Twitter, Yahoo...
Disadvantages1. Not everyone uses cookiesUnfortunately, some people set their browsers to deny cookies, because they consider them unsafe and dangerous. This means sites they will still end up getting asked questions every time (e.g. log in, layout, etc.).
2. Extra hassle for the site developerThey need to include code to set cookies, and if they change the site there is more possibility of a breakdown.
Remember -
Cookies are small files which save a value on your computer and send it to the server when you request a page from that server's site.
They are not viruses, and the law now states that a site has to notify you when it uses cookies.

What is difference between HttpModule and HttpHandler?
HTTP handlers are the end point objects in ASP.NET pipeline and an HTTP Handler essentially processes the request and produces the response. For example an ASP.NET Page is an HTTP Handler. HTTP Modules are objects which also participate the pipeline but they work before and after the HTTP Handler does its job, and produce additional services within the pipeline (for example associating session within a request before HTTP handler executes, and saving the session state after HTTP handler has done its job, is basically done by an HTTP module, SessionStateModule) HTTP handlers HTTP handlers are the .NET components that implement the System.Web.IHttpHandler interface. Any class that implements the IHttpHandler interface can act as a target for the incoming HTTP requests. HTTP handlers are somewhat similar to ISAPI extensions. One difference between HTTP handlers and ISAPI extensions is that HTTP handlers can be called directly by using their file name in the URL, similar to ISAPI extensions. HTTP Modules http://blbirajdar.blog.co.in HTTP modules are .NET components that implement the System.Web.IHttpModule interface. These components plug themselves into the ASP.NET request processing pipeline by registering themselves for certain events. Whenever those events occur, ASP.NET invokes the interested HTTP modules so that the modules can play with the request.

In order to get a code to post a picture on the internet, it needs to first be saved on the internet somewhere. In other words, it's not enough to just have it saved on your computer. Go to a place like imageshack.us or photobucket.com -- those are good sites for absolutely free web hosting.
When you upload it (follow the directions on the website) it will give you a URL for the picture -- like the web address for a web page, except it's an exact link to the picture itself. Copy and paste that code.
Then go to your web page (wherever you are entering your web coding), and use this code:
Just replace the URL HERE with that code you copied. Make sure to type in everything as is, with the "" and all. Hope that helps!
---------------------
create account in www.photobucket.com then if you have account upload images after that over your mouse in the picture you uploaded the URL links will appear then copy it!

Julie 102 12 5

How can you keep someone from viewing a website?
If you run a website, you can check by IP address or by cookie if they are the person you want to block and disallow them to view your site. If you want to prohibit them from viewing and you have control over the computer you use, installing a web filter will block them from viewing the site. Windows and several other companies have web filters you can institute.

Then login with the username you created earlier...
What is the difference between search engines and directory search engines?
Search engines are essentially algorithmically driven computer systems that reach out to the billions of websites on the Internet (called crawling) which is then stored for later use when someone runs a search. Popular examples include Google, Yahoo, Bing, and others. Directories are listings of websites, often by category, with information that is harvested by humans. The largest example of a directory is DMOZ. While searching directories can be a more arduous process than using search engines, they provide a high amount of relevance to those looking for information since the human component ensures that the listings are of great value.
HTTP is a text based protocol for exchanging data over a network, and the preferred protocol for the Internet (a.k.a. World Wide Web)
HTTP is synchronous: a client issues a request and waits for the corresponding response before anything else is done.
Asynchronous Javascript And XML (AJAX) is a way of using a HTTP request from the web browser to retrieve data using JavaScript, without leaving the current page. This use is said to be asynchronous because the JavaScript is making the HTTP request does not wait for the response, but instead continues any further necessary processing. A handler function is called to deal with the response, as and when it arrives.
So the real answer to the question as it stands is: HTTP is not asynchronous.
What is the difference between a search engine and a meta-search engine?
I think a meta-search engine uses another search engine/s to to look for its results so it does not have necessarily have to crawl and index all the Internet web pages.
How does a meta search engine work?
meta search engine is on page Seo , if you want to meta search engine work then you have analaysis website coding and check all meta keyword , this type you have to work in meta keyword.
You can clear the cache by going to the settings menu. In the settings menu. You will find a tab for clearing the cache.
How can you break website filter?
You can circumvent one by using a proxy server, but unreliable proxy servers have been known to upload malware, adware, spyware, and even viruses. Generally if you don't know how to do it safely, you should probably stick to what it will let you see.
