NAME

httpd::doc_error - Commands to generate error and not-found pages

The package httpd::doc_error provides a number of commands for the generation of standard error and not-found pages.

Doc_NotFoundPage virtual: Registers the url (virtual) and thus the file of the not-found page in the package httpd::doc. The contents of the file are always subst'ed to generate the actual reply send to the client. In other words, while there is basic templating for this page via httpd::subst the full-blown TML is not available here.
Doc_ErrorPage virtual: See Doc_NotFoundPage above, except for the error page.
Doc_NotFound sock: Called when a page is missing. Looks for a handler page registered with Doc_NotFoundPage, sets up the substitution context and then returns the result of the substitution run. The argument sock specifies the connection and request which asked for the missing page. A subst handler can retrieve the url which was not found via the command Doc_UrlNotFound below.
Doc_Error sock ei: Like Doc_NotFound, except that is called when an error occured while processing the request on connection sock. ei contains the error information to show in the page. A subst handler can retrieve this information via Doc_ErrorInfo below.
Doc_ErrorInfo: Returns the error information raised by the package.
Doc_UrlNotFound: Returns the url which was not found.
