Unable to access partial TMG in connect.qq.com through the

Before the implementation of some projects in the operation and maintenance of the process of customer feedback, the client through the TMG agent online, access to the QQ site http://connect.qq.com/, you can normally open the page, but if you click "Apply for Access", "My Application" and "Web Application" link, Can not open a child page, and will return an error message, information displayed as being TMG policy prohibited, the wrong process will be the user's machine to join the network and unrestricted access to the web and still can not normally open the relevant page, but in the absence of firewall settings in the environment is indeed open. Today, I would like to share with you the way we handled it, hoping to give a reference to my friends who have also encountered this problem.

The first cause of this problem is generally caused by the "compression filter" in the Web filter in TMG, and the following is a few Microsoft explanations for this filter:

An http/0.9 response has is a body, but no headers. The Web site closes the connection to indicate the end of a response.

However, the Compression filter Web filter in ISA Server expects a http/1.0 or http/1.1 response. The Compression filter Web filter does not recognize a http/0.9 response. Therefore, the Compression Filter Web filter assumes that connection are lost or reset before the Web site can send all The HTTP response headers.

We can turn this feature off to solve the problem by doing the following:

1, open the TMG console.

2, click (System) node, in the right control Panel to find a Web filter-> compression filter, right-click the filter and then click on the properties, and then remove the "Enable this filter" Before the tick, click OK, application can be.

Of course, disabling this feature may also cause other sites to appear abnormal, if you encounter the shutdown of this feature, other sites have an abnormal display, you can use the following methods to deal with:

1, first of all, to determine whether the system Windows XP, if it is necessary to check the IE6 "use HTTP1.1 in any through the proxy connection" this option, but if the I8 of Windows 7, this hook has been the default hook, so there is no this problem.

As for how to open this option under IE6, let me briefly say this here:

1, open IE Browser, click the Tools menu, choose Internet Options.

2, in the pop-up window, select the "Business-Class" tab, select "HTTP Settings" under the "use of HTTP1.1 in any through the proxy connection."

3, click the Confirmation button, exit the Internet Options window page, and then restart IE browser.

2, if still does not work, you can not turn off the "compression filter" function, the processing method can refer to the method shown by Microsoft KB944114.
