The HTTP reply message, may have different scheme/protocol from the HTTP request cause the reply. For example to an https://.... request we may pass to ECAP an HTTP/1.0 or HTTP/1.1 reply because of the SSL-bump. The protocol information included in HTTP replies. Currently we can recognize only HTTP 0.9/1.0/1.1 or ICY replies but these are the only replies which can be sent to ECAP... > > * If it is sending the scheme of the URL which the message was generated > *for* then the reply has a "request" member which can be used to access > the URL details of the request which triggered this reply. > > * If it is sending an indicator of what syntax message to parse, then > the http_ver member should be used instead for both requests and replies. > > * If it is sending the on-wire protocol used to communicate with the > current client or peer/server.

My opinion is that we need to send to ECAP the scheme of the url for HTTP requests and protocol information included in headers for replies. At least as temporary solution to allow ECAP compile for now, which also is compatible with the current behaviour. A virtual method provides these information for HttpMsg objects, I believe, it is a good solution. If we have problem with definitions, we can name it with a name different than the "HttpMsg::protocol()". eg HttpMsg::estimatedProtocol() or something like this... > > Amos > >
