This article mainly explains "how to solve the problem that port 80 cannot be accessed". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to solve the problem that port 80 is inaccessible.

Recently, it is said that port 80 of adsl has been blocked, and port 80 of many computer rooms and servers has been blocked, which is indeed a very depressing thing.

In general, port 80 cannot be accessed because the filed domain name has not submitted a whitelist. By default, port 80 is blocked in the computer room. You need to submit a record from the idc service provider. If the domain name is not licensed, you can only use other ports.

In the face of this kind of thing is really very helpless, in China, many people engaged in technology do not have the right soil. The saddest peanut shell is used as a dynamic domain name in China. This is an enterprise engaged in technology, and it does not involve any non-crab factor. Only to be fucked by this. All right, it's over. Peanut shells are mainly used for dynamic domain name resolution. A large part of them are adsl users, and blocking port 80 is undoubtedly the biggest blow to the enterprise.

Here are several ways to ease it a little bit. (the following scheme is only suitable for those who have administrative rights to the system, such as vps, their own servers, etc. If you are a virtual host, it will be useless if you can't change the port. )

1. Swap access port

Port 80 can not be used to change individual ports, this is the simplest, under the host setting, there is no technical content. The same effect is not good, which is equivalent to changing the domain name. Other people don't know, and they need to be notified one by one.

two。 Domain name forwarding

If your domain name is

Www.aaa.com, port 80 is blocked, you can enable other ports, such as port 800. put www.aaa.com

Jump to www.aaa.com:800, you can choose to hide forwarding and not to hide.

The feasibility of this scheme is relatively small, most of the domain names registered in China do not provide domain name forwarding, or forwarding or hidden forwarding have to be examined. For domain names registered abroad, the forwarding servers provided are almost sealed.

And the domain name forwarded affects the inclusion of search engines. It's just an emergency.

3. Domain name jump

Resolve the domain name to a host that does not seal port 80. Replace those with 80% seal with another domain name such as a.aaa.com.

Write a html,php or asp on the available host (see host support)

The jump code is as follows

ASP mode
