Base HREF is wrong when scripturls are changed

Some templates use %SCRIPTURL%/%SCRIPTNAME%/ to construct the base URL for this page. When one changes script-URLs (e.g., to get shorter URLs), that base URL is wrong and internal links fail.

Example case

Use a default 4.1.2 installation where URLs have been shortened according to the TWiki:TWiki.ShorterUrlCookbook.

Then a page will have the URL http://wiki.domain.tld/Web/TopicName. But page.pattern.tmpl will add the tag

   <base href="http://wiki.domain.tld/view/Web/TopicName"></base>
at the top of the page. This base href is used for topic-internal links, e.g., for the table of contents.

At best, this leads to a superfluous reload, since the internal links refer to a different URL (/view/Web/...) than that of the current page (/Web/...).

At worst, there is no RewriteRule/ScriptAlias for /view/ defined and all links in the table of contents cannot be resolved and lead to 404 not-found errors.

Proposed Solution

Use %SCRIPTURL{%SCRIPTNAME%}% instead. Every working scripturl setup has adapted $TWiki::cfg{ScriptUrlPaths}{view} or whatever script URL it changes.


I attach a patch to the 4.1.2 codebase that changes all existing base hrefs accordingly.


I don't know if a bug in the distributed basic skins categorizes as Engine or Extension, so I leave it at Engine. smile

If you need an Internet-accessible 4.1.2 installation to test that bug (for some time), I can make that available.

See my latest comment in TWiki:TWiki.ShorterUrlCookbook. It might serve as a permanent solution for short urls. smile

Sorry, but AFAICS your comments are not relevant for this bug: you still keep the /view action prefix in your proposal, i.e., you just work without .../bin prefix in front of /view. This bug is about wrong base hrefs if you have discarded the /view prefix, too.

Thanks Joachimn, I applied your patch on MAIN branch (for 4.2)
