[TYPO3-core] RFC Bug #11009: External Links get prepended with http://typo3 in the RTEhtmlarea in Firefox 3.0.11/3.5b4

[Oliver Hader]

This is an SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=11009
https://bugzilla.mozilla.org/show_bug.cgi?id=481647

Branches: TYPO3_4-1, TYPO3_4-2, Trunk

Problem:
Since the release of Firefox 3.0.11 external links get prepended by the
current base URL and produce a wrong URL in the RTEhtmlarea.
For example an external link to "http://www.google.de/" becomes
"http://website.com/typo3/http://www.google.de/".

Solution:
In RFC #9196 a special handling for IDN domains in Firefox (e.g.
"www.müller.de") was integrated - the link was encoded by using
encodeURIComponent(). However, in Firefox 3.0.11 internal frames use
something similar to a base URL that automatically prepends relative URLs.
Since encodeURIComponent() escapes "http://" to "http%3A%2F%2F" the link
is recognized as relative URL. Using encodeURI() instead works since
"://" will not be encoded.
encodeURI() still solves the mentioned issue of RFC #9196 for IDN
domains. Thus, everything should be fine again.

Notes:
Thanks to everybody investigating this issue.
Attached is a patch for TYPO3 4.1 (with a compressed script) and another
patch for TYPO3 4.2 & 4.3.
