[SQU] Problems with some URLs - too long?

I have a number of sites using a FreeBSD box with ppp
as a DSL router/firewall. http through the firewall is
handled by squid while all other traffic goes out via
ppp's nat facilities.

At one site, certain links don't work -- the browser
(both Netscape & MSIE) hold up the hourglass until the
request times-out. If I switch from proxy to a direct
connection via Dial-up Adapter, I get the requested
page without problem. The links aren't to one
particular site; there are a few troublesome sites and
only a few links on those sites don't work.

For example, at one site if I search for a product and
it returns the first page of many then the links to
subsequent pages don't work. Looking at the source for
that page, the only thing unusual about the links is
that they are very long. Here's the link to go to
search results page 4 (wrapped each 50 columns for
readability and with the actual site masked out):

   http://XX.XXXXXXXXXXX.com/search/0,,,FF.html?incjs
   p=Results.jsp&keywords=ups&tab=startTab&pStart=0.0
   0&pStop=0.00&oStock=0&oPromo=0&oAuth=0&nSpOr=0&nCo
   ns=0&nDisc=0&langCds=&langAvail=&uID=FTE0400197846
   3735403&hits=50&page=4&sort=PRODUCTDES&flow=-1&jum
   p=&cat=&subcat=&vendor=&media=&platform=&sn=301LQS
   AVSU&db=ecremmoCbeW_REMA&cache=900

After the link times-out I get the following message in
the access.log file:

   978466382.562 120732 192.168.0.13 TCP_MISS/500 994
   GET http://XX.XXXXXXXXXXX.com/search/0,,,FF.html? -
   DIRECT/XX.XXXXXXXXXXX.com -

Does anyone have any ideas why these URLs won't go
through squid? Are they too long for the proxy
protocol used between the browser and squid?

Thanks in advance,

Andrew.
