When TCP::Collect is used with 'skip' and 'length' arguments in SERVER_CONNECTED, the "skip' argument does not take effect and is ignored. The Collect works, but collects only the length bytes from start.
TCP:Collect collects bytes without taking into account the skip, so the bytes collected are not the correct ones.
TCP:Collect on server side events like SERVER_CONNECTED used with the 'skip' parameter. This is an intermittent issue that have happen only with IIS server.
None.
The settings for TCP::Collect command skip and length arguments are now honored during packet processing.
