Combining multi-value headers

HTTP protocol allows for certain headers to appear in the message multiple times. Namely, multiple headers with the same header name are permitted if that header field is defined as a comma-separated list. The standard specifies that such fields can be combined in a single header: value pair, by appending each subsequent field value to the previous one, each separated by a comma.

Pound is able to perform such combining on incoming requests as well as on responses. To enable this feature, declare names of headers that can be combined using the CombineHeader statement, e.g.:

    CombineHeaders
	"Accept"
	"Allow"
	"Forwarded"
    End

Pound distribution includes file mvh.inc which declares all multiple-value headers in a form suitable for inclusion to the main
pound configuration file. This file is installed in the package data directory, which is normally /usr/local/share/pound or
/usr/share/pound, depending on the installation prefix used.

SNI in HTTPS backends

New directive ServerName is provided for use in Backend section after the HTTPS statement. This directive sets the host name to be used in server name identification (SNI). Its argument is a quoted string specifying the host name. This directive also rewrites the Host: header accordingly. Example usage:

    Backend
	HTTPS
	Address 192.0.2.1
	Port 443
	ServerName "www.example.org"
    End

Cert statement in ListenHTTPS section

Argument to the Cert statement in ListenHTTPS section can be the name of a directory containing certificate files. All files from that directory will be loaded.
