[Mediawiki-l] Internal link with query string?

[Daniel Barrett]

What is the right way (in wikitext) to produce an internal link with a
query string?  I am trying to make a link to a custom special page that
accepts query parameters:

  Please visit our [[Special:Foobar?arg=$1|new special page]].

but unfortunately this link renders as:

  http://mywiki.com/wiki/Special:Foobar%3Farg%3D%241

with the "?" turned into %3F, so it isn't recognized as a query string.

If I use an external link instead:

  [{{SERVER}}/wiki/Special:Foobar?arg=$1 new special page]

this breaks when $1 contains whitespace.

Thanks,
DanB
