HTTP && TCP filter
Why using this filter returns packets with HTTP and OCSP protocol? I thought the AND operator returns anything only when both conditions are true?
There is a sample capture attached to this issue (#15674)
If you look at View-> Protocol Hierarchy
it shows Online Certificate Status Protocol
under Hypertext Transfer Protocol
Or select one of the OCSP packets, expand Frame
and look at
[Protocols in frame [truncated]: eth:ethertype:ipv6:tcp:http:ocsp:ocsp:x509sat:x509sat:x509sat:x509sat:x509sat:x509sat:x509sat:x509sat:x509sat:x509sat:x509sat:x509sat:x509sat:x509sat:x509sat:x509sat:x509sat:x509ce:x509ce:ocsp:pkix1implicit]
tcp:http:ocsp:
This was only implied, but for clarification Wireshark display filters are used to include or exclude each packet depending on whether it has the fields or field values specified in the filter, thus a filter of HTTP will include all packets containing protocols that an on top of http as all such packets contain the "field".
