12 (0xC) Resource not found

Description

The file pointed by the URL cannot be found.

Probable causes

See also error 6. This error is very similar to the HTTP 404 error, but note that this error will be issued if only the file name portion of the URL is not found - if the URL points to a directory that exists but the file specified in the URL is not there. If the path portion of the URL is also wrong (i.e. does not exist) error 6 will occur instead.

ALP 1.2 and later handles this event and you are allowed to specify error handler page. However notice that in contrast to WEB servers you can handle only "File not found" errors concerning the file portion of the URL. This is so because ALP "sees" the computer's file system as a set of Virtual ALP sites designated by the alp.site files found in some directories. Therefore a wrong path portion of an URL makes the Virtual ALP site detection not always possible and thus ALP cannot determine in which Virtual ALP site to seek for error handler. To avoid problems caused by wrong site context the custom error handling is limited to the file portion of the ALP URL.
