[Zope] A nice problem with url_quote_plus

[Nbk]

  Hi.

  I have the folowing code in one of my DTML method's:

  <dtml-call "RESPONSE.redirect(_.string.join([url,query],''))">

  'url' and 'query' are two variables passed by the REQUEST. This work's just fine,
but with some minor :-) problems in my case. If i have a 'query' with some spaces,
the RESPONSE.redirect causes an obvious http error. So, i want to replace some 
characters of my 'query' variable. And guess what? <dtml-var url url_quote_plus> 
gives me the right string. How do i do an "quote_plus" ( like in python urllib module )
in Zope, without using an External Method?

  BTW, i've used an python method, but with no luck ( i can't make a 
simple "import urllib").

TIA,

@886, Nbk ( Just believe, Zope source code is the best place to find up-to-date
documentation! )

P.S. - I've looked up for the solution in www.google.com, www.egroups.com, 
lists.zope.org, www.zope.org, www.python.org, and some other resources. 
I had find some interesting ideas, but none of them are usefull to this problem. :-)
