In contrast to using the Page HTML Compression Web.Config option, the MakeResponseCompressed method allows you to enable HTML compression for individual web pages.

This method overload allows you to control whether to enable page HTML compression for Internet Explorer 6.

Note that in version v2010 vol2, we decided to suppress our internal HTTP compression (controlled by the Page HTML Compression config option) for IE6. This is due to different unpredictable problems that occurred in IE6 with enabled compression.

In some application scenarios however, it may be required to have response compression enabled for all browsers including IE6.

For such scenarios, we provide a way to activate compression by using this MakeResponseCompressed overload, accepting a Boolean parameter. This parameter allows our internal response compression to be always switched on, without checking client browser versions. It is necessary to call this method in the Application_PreRequestHandlerExecute event (Global.asax).

void Application_PreRequestHandlerExecute(object sender, EventArgs e){

Using this method makes all responses sent from the server (whether they were requested via callbacks or not) compressed.
