TCL Format

Each TCL file is a list of entries of the following form:

$<$${\it URL}_1$$>$

$\vdots$

$<$${\it URL}_n$$>$

where each $<$${\it URL}_i$$>$ is a URL of one of the following forms:

• http://$<$host$>$[:$<$port$>$]/$<$path$>$
• file://[localhost]/$<$path$>$

Each URL specifies either a single file or the root of a directory tree from which it is permissible to download code (via a LOAD command) to be executed by Anetd. A list of URLs in a single TCL entry is interpreted as a list of alternate (mirror) servers from which Anetd may try to download code in the event that one of them is inaccessible. HTTP URLs normally refer to remote hosts (often managed by the ABOCC), while file URLs refer to the host on which Anetd is running.

Anetd 1.6 will also read legacy TCL files, where each entry is simply the hostname of a code server, but their use is deprecated. Support for legacy TCL files will be removed in a future version of Anetd.
