3.4 brings changes to the helper protocol syntax. There were some
parsing issues in the betas. Please try an upgrade to the 3.4.3 release,
most of the teething problems have been resolved there.

Please also note that the helper was not sending back to Squid valid
response syntax to begin with. Responses to 3.2 should have been either
a blank line or just the new URL. The extra text sent on teh end of the
request lines should NOT be echoed back out at Squid.
