It would look like this when the original url where considered
"relative" (as the browser would prepend the base url).

To find out whether the "[URLofPlaceLinkWasClickedOn]" prefix
was provided by Plone or the browser, you could look
at the pages source code (browsers usually provide a means
to get at the (HTML) page source). If you see there
a relative url (one not starting with a protocol), then the browser
has provided the prefix - otherwise, it has been Plone.

[P]
In the page source, it actually has the link as http:\\[hostname]\[wherelinkshouldgo]

[dm]


But, it may not be relevant who (browser or Plone) has provided
the prefix. The likely problem is in your external links - they
likely use faulty urls.

According to RFC 2396 (the Uniform Resource Identifier (uri) standard;
urls are some form of uris, thus covered also by this standard),
there are three types of uris/urls:

  *  absolute (they begin with "<protocol>::")
  *  host relative (they begin with "/")
  *  and relative

Relative uris/urls are resolved with respect to the base uri/url
(this means "[URLofPlaceLinkWasClickedOn]" in your case),
host relative uris/urls are resolved with respect to the
host from which the page was obtained (this means "[YourHost]" in your case).

>From this description, you can see that (standard conform)
"external" uri/urls must start with "<protocol>::".


Thus, making the urls in your link objects (and elsewhere) standard conformant
will (almost surely) solve the problem.

[P]
That does definitely solve the issue, but it has to be done manually; I can definitely enforce the users putting in links correctly now, since TinyMCE makes you pick a protocol, as for the others, I've got the redirect rule as a temporary fix until he various external links are all updated

Thanks for the help

Cheers,
Phillip
