[SQU] missing-http-ident ?

Hello all,

        Has anyone else seen this problem, and perhaps more importantly,
does anyone know of a solution? Going to http://www.metacrawler.com (a
popular search engine) and doing a search for "html java" will produce
the following error :

---------------------------------------------------------------------------
The requested URL could not be retrieved

While trying to process the request:

GET http://ad.doubleclick.net/adj/N1713.go2net/B23532.9;abr=!ie;sz=468x60;[
keyword];ord=35687 HTTP/1.0

User-Agent: Mozilla/4.75 [en] (X11; U; Linux 2.2.16 i686; Nav)

        ... etc ...

        At the same time this error message appears, a "missing-http-ident"
appears in the Squid logs. It looks like there's a carriage return in the
URL which is causing Squid grief. Is there a way to tell Squid to ignore
the CR? I have tried the various permutations of the uri_whitespace option,
both in Squid 2.2.STABLE5 and 2.3.STABLE4 (which allows for the 'strip'
setting), both give me the same results ("Invalid Request"). This is what
have found so far :

* MS IE 5.x users are unaffected. I have not tested other versions of IE.
* Netscape 3.x & 4.x all exhibit this problem, whether under Win32 or Linux.
* Both browsers work fine when retrieving the URL directly (no proxy).
* For Netscape users, disabling javascript will enable page to be displayed
  without Squid complaining, but I really don't want to tell users to disable
  javascript everytime they run into this problem (rare as it may be).

        So it looks like it may be a problem between Squid, and Netscape's
handling of javascript. I don't know if other browsers are affected as well
because I haven't tested them, but at this point I'll be happy if I can get
Netscape to work. Any thoughts?
