Sorry. I should have clarified. I have tried this on the latest versions

   squid-2.4.STABLE2
   squid-head-200109192301

I tested via the broken app, and directly using telnet like below...

localhost% cat request
GET http://www.mywebserver.com/abc/def/news_en_s.html HTTP/1.0
Referer: http://www.mywebserver.com/
host: www.mywebserver.com:80
Accept-Language: en-gb,en;q=0.5
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)
Connection: close
Accept: */*
Accept-Encoding: gzip, deflate
Content-Length: 0

localhost% telnet www.mywebserver.com 80 < request

Squid is transparently caching - it always goes direct if the C-L:0 line is in. If I remove it everything works fine.

Is there a better way of fixing this right now than my code hack in client_side.c ?

thanks
