Any idea to workaround and trick this request ? or it just some typos in HTTP header ?
Most likely a malfunctioning webserver returing invalid HTTP responses having whitespace in header names.
Confirmed. When sending your request the to web server in question the server response reads
HTTP/1.1 200 OK
Date: Sun, 26 Dec 2004 21:33:35 GMT
Server: Apache/1.3.26 (Unix) PHP/4.3.1 mod_throttle/3.1.2 mod_become/1.2
X-Powered-By: PHP/4.3.1
P3P : CP="ALL CURa ADMa DEVa TAIa OUR BUS IND PHY ONL UNI PUR FIN COM NAV INT DEM CNT STA POL HEA PRE LOC OTC"

As you can see the P3P header is malformed with a space before the :, and very recent snapshot releases of Squid-2.5 detects this protocol violation and rejects the response to ensure reliability in the HTTP protocol processing.
