Some time ago Access We ServiceTool It was very slow, so I pulled the fiber of telecom. Now both the lines of China Telecom and China Netcom have IP addresses and gateways respectively, but I don't want others to use two addresses. Access Such as Sina, whether through China Telecom or China Netcom Access And the speed can be balanced.
Later, I consulted many people in the industry. The basic solution was to use CDN. Technology But because of the high cost, the company could not immediately approve it, so this solution gave up. Another solution is to use the dns acl and view as the China Netcom Telecom IP address. Automatic But because the operations are complex, and the North and South must be updated from time to time Network IP Database And finally gave up.
HTML solution:
Access through a default homepage User And then turn to different addresses to reach a relatively ideal speed.
Operation and implementation:
The following section describes Code Save the token as default.htm and put it in your root directory on the default homepage, Set This is the first access. Then the user will first access this File Then, a judgment is generated. The Telecom user points to the specified Telecom domain name, And the Netcom user points to the Netcom domain name.
The method is as follows: Resolve a domain name, such as www1.xxx.com to the IP address of China Netcom, resolve a www2.xxx.com to the Telecom IP address, and bind the two domain names to an Apache/ IIS . At this time, the two domain names access the same website, but it does achieve the effect of North-South traffic distribution.
First, log on to the background of the service provider that you purchased the Domain Name Management , Add a record and point to it. Then, return to your server and add the forward and reverse resolution.
WWW in a Netcom IP
Www1 in a Netcom IP
Www2 in a Telecom IP Address

China Netcom IP in PTR www.xxx.com
China Netcom IP in PTR www1.xxx.com
China Telecom IP in PTR www2.xxx.com

The default.htm file code is as follows:
