Add protocol handler flag `PROTOPT_CONN_REUSE` to indicate that the protocol allows reusing connections for other tranfers. Add that to all handlers that support it. Create connections with `conn->bits.close = FALSE` and remove all the `connkeep()` calls in protocol handlers setup/connect implementations. `PROTOPT_CONN_REUSE` assures that the default behaviour applies at the end of a transfer without need to juggle the close bit. `conn->bits.close` now serves as an additional indication that a connection cannot be reused. Only protocol handles that allow reuse need to set it to override the default behaviour. Remove all `connclose()` and `connkeep()` calls from connection filters. Filters should not modify connection flags. They are supposed to run in eyeballing situations where a filter is just one of many determining the outcome. Fix http response header handling to only honour `Connection: close` for HTTP/1.x versions. Closes #19333 |
