2. In the Content Offset field, enter the number of bytes to be ignored starting with the first byte

of the Message body, after the empty line (CR,LF,CR,LF) between the headers and the body

of the message. Valid entries are from 1 to 255 bytes.

Content Length The content parse length is used for application inspection decisions.

this field must be less than the number entered in the Content Length Higher Value field.

2. In the Content Length Higher Value field, enter the highest number of bytes to be used

for this match condition. Valid entries are integers from 0 to 4294967295. The number in

this field must be greater than the number entered in the Content Length Lower Value

field.

Content Type

Verification

Verification of MIME-type messages with the header MIME-type is to be used for application

inspection decisions. This option verifies that the header MIME-type value is in the internal list

of supported MIME-types and that the header MIME-type matches the content in the data or body

portion of the message.
