Help! I am having problems sending post data through a webform through squid. If I turn off the proxy and go direct it works. I see the post in the squid access logs, 1151512753.833 3114 10.10.121.203 TCP_MISS/502 1540 POST http://zip4.usps.com/zip4/zcl_1_results.jsp mmendelsohn DIRECT/56.0.134.62 text/html However when I isolate the packet in tcpdump, the connecting server sends me a RESET packet. 12:34:53.729409 IP zip4.usps.com.http > FTWPSINFPXY01out.41975: S 2519078180:2519078180(0) ack 97214157 win 8190 <mss 1380> 12:34:53.729430 IP FTWPSINFPXY01out.41975 > zip4.usps.com.http: . ack 1 win 5840 12:34:53.729831 IP FTWPSINFPXY01out.41975 > zip4.usps.com.http: P 1:549(548) ack 1 win 5840 12:34:53.729937 IP FTWPSINFPXY01out.41975 > zip4.usps.com.http: P 549:618(69) ack 1 win 5840 12:34:56.727686 IP FTWPSINFPXY01out.41975 > zip4.usps.com.http: P 1:618(617) ack 1 win 5840 12:34:56.729163 IP zip4.usps.com.http > FTWPSINFPXY01out.41975: R 1:1(0) ack 1 win 5840 All I get is the page The requested URL could not be retrieved ________________________________________________________________________ _____________________________________________ While trying to retrieve the URL: http://zip4.usps.com/zip4/zcl_2_results.jsp <http://zip4.usps.com/zip4/zcl_2_results.jsp> The following error was encountered: * Read Error The system returned: (104) Connection reset by peer An error condition occurred while reading data from the network.
