In order to interface our TWiki with a mailing list archive, I embed the mailing list HTML pages in TWiki topics using the INCLUDE variable. However, the processing of the included pages breaks the links. For example:

The page /list-archive/msg00000.html (the first message in the archive) refers to the next message as msg00001.html. However, after processing by INCLUDE, the link is turned into: /list-archive/msg00000.html/msg00001.html This obviously doesn't work. Using rhe raw parameter is not an option, as the links do need to be processed (otherwise the server would look for the next message in the TWiki /cgi-bin/twiki/bin/view/... directory).

This is reproduced here. The following link is in an included page that contains a link that is relative to the server where the included page resides.

Levien further points out that the documentation states:

When a page is included, normally TWiki will process it, doing the following: 1) Alter relative links to point back to originating host, 2) [...]

I have checked this behaviour in TWiki-3 (Cairo) and it is consistent, so this is not a TWiki-4 problem.

Support rewriting HTML URL references in included pages.

This would obviously impact A, IMG, SCRIPT and any other HTML tag that supports URLs.

I think this little patch is all that is needed, rest of the url rewriting work is working as it should.
