First point: The site relative address problem caused by numerous dead links

Every site owner knows that frequent viewing of the site has a dead link is a routine maintenance work, however, the most likely to cause a dead link problem is avoidable, which seems to be simple, but the use of this link can reduce the occurrence of dead links from the source.

Another option is to use absolute address, example <a Href=http://www.2guys.cn/index.asp>2guys station </A>, many sites have used absolute web address, However, this will make the test process of the Web page more complicated, so many web designers prefer to use relative addresses.

A relatively flexible solution now is "absolute relative link" (differs relative link), or "Server relative link" (server-relative), "Relative Domain name link" (domain-relative), It is a mixed version of the relative address and absolute address, and an absolute relative link includes an initial backslash to tell the server which root directory to start with and track the path. For example: <a href= "/articles/f20070726.html" >f20070726</a>.

This is a more flexible way to make web designers more like, so that they can test and upload the Web page without the error caused by the domain name can not be displayed problems.

Will search engines think of "www.2Guys.cn" and "2guys.cn" as two sites? The answer is yes. What happens if you ignore the problem? If you don't redirect one of the domain names to another, search engine will take these two domains under the Web page as a separate two sites, which is to say, the search engine that your site has a copy of the page, serious words is the whole station to replicate the problem, the consequences will be down the right penalty even in the search engine to delete the page.

The best way to search engine friendliness is to create a 301 permanent redirect that permanently points one domain to another. While Google has a webmaster tool that allows you to submit a specific URL as your preferred option, other search engines do not have this service.

About 301 of the Apache server and asp,php settings, etc. there are many online, you can search the Internet, here to say how to set the 301 DNS alias?

The following methods: <table width= "50%" border=0> <tr> <td>www.2Guys.cn</td><td> A </td><td >AAA.BBB.CCC.DDD (direct IP address) </td> </tr> <tr> <td>www.2Guys.cn</td><td> CNAME </td><td>www.2Guys.cn</td> </tr> </table>

This tells everyone (not just browsers and search engine bots) 2guys.cn is first name, www.2Guys.cn is 2guys.cn alias.
