Advanced Expressions: Parsing
HTTP, TCP, and UDP Data
You can configure advanced expressions to parse the payload for HTTP requests
and responses, including headers and body content. For example, you can ensure
that an HTTP request or response contains a header of a particular type, or you
can extract a particular segment from a URL path. You can also configure
expressions to transform the URL encoding and apply HTML or XML “safe”
coding for subsequent evaluation.

Similarly, you can analyze the payload in a TCP or UDP packet using an
advanced expression. For example, you can extract the source or destination port
and evaluate DNS record types.
