DYCONF specifies configuration parameters to be loaded dynamically on the beginning of relaying application protocol after the acception of a TCP connection from a client before starting a session over it. The loading of parameters can be conditional based on the specified conditions, and the parameter value can be generated and/or evaluated on each loading.

A condition for loading can be based on the identity (address or name) of the host of a client which is requesting over the new connection. Or it can be based on the content (sub-string or pattern) of the initial request data which is sent from a client over a connection. The request data is polled for a specified period (15sec. by default) and peeked by a specified size (4K bytes at max. by default).

Conditions:

qstr/string ... matching by request sub-string

qreq/pattern ... matching by request pattern

{from/hostList} ... matching by client hosts

excl[/number] ... exclusive with other DYCONFs

poll/seconds ... timeout of polling request [4k]

peek/bytes ... max. bytes of peeking request [15.0s]

skip ... purge peeked data before starting relay

debug ... enable logging for debugging of DYCONF

Example:

DYCONF="file:path.txt" # load parameters from path.txt
DYCONF="cgi:path.cgi" # load parameters generated by path.cgi
DYCONF="qstr/string,arg:{SERVER=tcprelay://sv1:1234;TIMEOUT=io:3}"
DYCONF="{qrex/[a-z][0-9]*},arg:{SERVER=tcprelay://sv1:1234}"
