Re: [squid-users] Request header

In src/client_side.c, try changing

From:

                debug(33, 1) ("Request header is too large (%d
bytes)\n",
                    (int) conn->in.offset);

To:

                debug(33, 1) ("Request header is too large (%d
bytes)\n%s\n",
                    (int) conn->in.offset, conn->in.buf);

Regards
