internet explorer and the RST packet. Tuesday, November 13, 2007 |
Internet explorer, for reasons unknown, will send a RST instead of tearing down a connection correctly.
Sometimes.
If you direct it to the root directory of a server, (http://brainproxy.com/), it seems to close the TCP connection fine.
However, if you point to a specific file, (http://brainproxy.com/somefile.txt), it will send an ACK, then a RST after the server sends its FIN packet.
Firefox, of course, gracefully closes the connection, per the RFC.
