SiteC Linkchecker

SiteC is equipped with a linkchecker that is able to check certain links for existence. Its operation mode is defined in the ~user/.sitecrc configuration file:

• linkcheck = off
  Linkchecker disabled.
• linkcheck = relative
  Default: In this mode, the linkchecker only checks "relative" URLs (such as HREF="sitec/index.html" without the protocol prefix (http:, ftp:, mailto:, ...).
  Fully qualified URLs (for example HREF="mailto:fraber@cs.tu-berlin.de" or HREF="http://www.cs.tu-berlin.de/~fraber") are interpreted as "external" to the server and not checked.
• linkcheck = all
  Not in this release, coming soon: In addition to checking relative URLs, "external" URLs are verified over the network.

At some WWW-sites, URLs are mapped to pathes using a server configuration file (called "srm.conf" for Apache). To reflect such a mapping, an optional mapping file can be specified in ~user/.sitecrc (called "basemap.map" by default).

Basemap.map is composed of lines, beginning with the keyword "Alias" and containing the URL and the corresponding path, separated by whitespaces:
