No Squid does not affect the upload data. It is relayed as received.

You will need to identify the difference between POST/PUT requests
which are succeeding and those which are failing. This may require a TCP
packet trace from between the clients and Squid (use "tcpdump -s 0 ..."
to get all the headers).
  I suspect you will find the HTTP/1.1 Expect feature being sent in the
failing requests (no body data gets sent until after a timeout or 100 /
417 message exchange).

Please also identify which Squid release number you are using.

   ---> ... here. Below the security protection rules that prevent
network attacks.

NOTE: Having the last rule in your config a "deny ..." rule means
anything not already blocked is allowed.
   You should finish the http_access rules with "http_access deny all"
