Payload matching via single pass transformation of HTTP payload

机译:通过HTTP有效负载的单遍转换实现有效负载匹配

摘要

In an embodiment, a method of payload matching via a single pass transformation of an HTTP payload includes receiving a payload packet destined for a recipient and parsing the payload packet in a single scan of the packet using a combined regular expression. The combined regular expression includes a plurality of regular expressions that correspond to a set of replacement rules. The method includes determining a scatter-gather list conforming to the rule, constructing a new payload packet based on the scatter-gather list, and sending the new payload packet to the recipient.
