This article uses easy-to-understand examples to introduce why the www domain name cannot be accessed. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

The domain name without www cannot be accessed, often because the domain name with www is not added to the rule when the domain name is bound. As a result, the domain name with www is not recognized by the host, and the domain name cannot be accessed.

The solution to the problem that domain names cannot be accessed without www is to go to the virtual host management center, domain name binding, and add the domain name with www.

That is, both a.com and www.a.com are bound to the host.

Then go to the domain name management center, find the domain name resolution function, and see if there are two domain name resolution records, one is www and the other is @. If any is missing, complete it.

That is, the hostnames are www and @, respectively, and the corresponding types are set to CNAME, corresponding to the values, and enter the same virtual host. Some cloud service providers will provide a secondary domain name for temporary testing and backup. For example, there will be a second-level domain name of xxx.gotoip*.com for each virtual host. When we enter the corresponding value, we can enter this second-level domain name.

After binding and parsing, we enter a.com and www.a.com, and find that they are all accessible.

At this point, the problem of why domain names without www cannot be accessed has been basically solved. However, we usually use the domain name of www as the home page, which will show that the two domain addresses point to a home page, which will spread the weight. if it is a Linux virtual host, you can go to the root directory and make a 301 rule in the .htaccess file. Set the a.com and www.a.com rules and specify to jump to a page. At this point, it's all settled.

About why not www domain name can not be accessed to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
