Delete Internet Explorer Redirect URLs
Redirects
Redirects (URL redirection), also called URL forwarding, domain redirection and domain forwarding, is a technique on the World Wide Web for making a web page available under many URLs.
Purposes
There are several reasons to use URL redirection:
Similar domain names
A web browser user might mis-type a URL -- for example, "exampel.com" and "exmaple.com". Organizations often register these "mis-spelled" domains and re-direct them to the "correct" location: example.com. For example: the addresses example.com and example.net could both redirect to a single domain, or web page, such as example.org. This technique is often used to "reserve" other TLDs with the same name, or make it easier for a true ".edu" or ".net" to redirect to a more recognizable ".com" domain.
Moving a site to a new domain
Why redirect a web page?
* A web site might need to change its domain name.
* An author might move his or her pages to a new domain.
* Two web sites might merge.
With URL redirects, incoming links to an outdated URL can be sent to the correct location. These links might be from other sites that have not realized that there is a change or from bookmarks/favorites that users have saved in their browsers.
The same applies to search engines. They often have the older/outdated domain names and links in their database and will send search users to these old URLs. By using a "moved permanently" redirect to the new URL, visitors will still end at the correct page. Also, in the next search engine pass, the search engine should detect and use the newer URL.
Logging outgoing links
The access logs of most web servers keep detailed information from where visitors came and how they browsed the hosted site. They do not, however, log which links visitors left by. This is because the visitor's browser has no need to communicate with the original server when the visitor clicks on an out-going link.
This information can be captured in several ways. One way involves URL redirection. Instead of sending the visitor straight to the other site, links on the site can direct to a URL on the original website's domain that automatically redirects to the real target. This added request will leave a trace in the server logs saying exactly which link was followed. This technique is also used by some corporate websites to have a "warning" page that the content is off-site and not necessarily affiliated with the corporation. This technique does bear the downside in the delay of an additional request to the original website's server. For websites that wish to display a "warning" page before automatically forwarding, the length of time the warning is displayed is an additional delay.
Short, meaningful, persistent aliases for long or changing URLs
Currently, web engineers tend to pass descriptive attributes in the URL to represent data hierarchies, command structures, transaction paths and session information. This results in a URL that is aesthetically unpleasant and difficult to remember. Sometimes the URL of a page changes even though the content stays the same.
Manipulating search engines
Some years ago, redirect techniques were used to fool search engines. For example, one page could show popular search terms to search engines but redirect the visitors to a different target page. There are also cases where redirects have been used to "steal" the page rank of one popular page and use it for a different page, usually involving the 302 HTTP status code of "moved temporarily."
Search engine providers noticed the problem and took appropriate actions. Usually, sites that employ such techniques to manipulate search engines are punished automatically by reducing their ranking or by excluding them from the search index.
As a result, today, such manipulations usually result in less rather than more site exposure.
Satire and criticism
In the same way that a Google bomb can be used for satire and political criticism, a domain name that conveys one meaning can be redirected to any other web page, sometimes with malicious intent.
Manipulating visitors
URL redirection is sometimes used as a part of phishing attacks that confuse visitors about which web site they are visiting.
