What this page refer to is the Host header rearrangement done by squid-2.5.STABLE3 and earlier and which was found to cause some broken web servers / firewalls to break in different manners. More information on this issue can be found from the Squid-2.5 bugs page <url:http://www.squid-cache.org/Versions/v2/2.5/bugs/#squid-2.5.STABLE3-hostheader>
Please note that this is not a Squid bug but yet anoter case of broken firewalls which should be thrown out with yesterdays garbage (or at least the failing function should be immediately disabled). It is truly amasing to see such critical bugs in high profile web site implementations, and even more amasing there apparently is vendors who dare to sell such equipment/software claiming it works fine for such use.... but I guess the high profile web sites trusts big vendors to make correct solutions and don't even bother to verify the functionality before going into production.
