policy enforcment if content type is derived from requested URL path

hi friends

i am new to TMG and i am trying hard to Learn it.

in TMG Administrators Companion book, in page 253, under the title "Policy Enforcement in Certain Scenarios" we read :

 

"However, in certain scenarios, the content type can be derived from the requested URL path, and then this information will be used to match the policy. No renegotiation will be performed with the Web server."

i don't understand this sentences. can anyone describe me in simple words and with a simple examples ?

thanks very much in advance

Hi,

Based on my knowledge, Content Type specifies the content type of HTTP response and its contained in the URL access-type. If you do not specify a Content Type, it defaults to text/HTML.

For an existing connection where HTTP PAYLOAD is carried, if you add a new rule to allow access only for specific content types, the request for the earlier allowed content type will be denied and the connection will be terminated.

When client (access external site via TMG) requests a new content type in an existing HTTP connection, the TMG Policy Enforcement of existing connections uses the content type which is derived from the requested URL path to match the policy rather than renegotiating the establishment of the connection with the Web server.

The links bellow maybe helpful to better understand TMG Policy Enforcement:
