[squid-users] problems with some requests

Hi,
I have a problem with ftp and https requests.
I'm running squid in debug mode to trace function calls for a ftp and a
https request and finding below lines in cache.log:

for a https request I'm getting:
**************
client_side.cc(2862) clientParseRequests: local=216.239.32.20:443
remote=10.1.116.50 FD 10 flags=17: attempting to parse
HttpParser.cc(29) reset: Request buffer is 

HttpParser.cc(39) parseRequestFirstLine: parsing possible request: 

HttpParser.cc(248) HttpParserParseReqLine: Parser: retval -1: from 0->49:
method 0->-1; url -1->-1; version -1->-1 (0/0)
**************
In fact the request is unrecognizable for squid.
and for a ftp request:
**************
AsyncCall.cc(30) make: make call ConnStateData::clientReadRequest [call39]
AsyncJob.cc(117) callStart: ConnStateData status in: [ job3]
client_side.cc(2923) clientReadRequest: local=10.1.116.49:22
remote=10.1.116.50 FD 10 flags=17 size 0
client_side.cc(2959) clientReadRequest: local=10.1.116.49:22
remote=10.1.116.50 FD 10 flags=17 closed?
client_side.cc(2401) connFinishedWithConn: local=10.1.116.49:22
remote=10.1.116.50 FD 10 flags=17 closed
comm.cc(1102) _comm_close: comm_close: start closing FD 10

That's very wonderful! squid could not read request from socket!

here is my config file:
**************
