Hi
Would anyone please like to help me on the following issue?
I have accessed http://kb.com/kbp/index.html and then trying to play the
video through quicktime.
If I am not trying through proxy server, where squid (STABLE 11) is running,
video is getting played fine.
However while I am trying through proxy, connection is not getting
established.
Using ethreal I have found following information:
During connection initialization I am getting a HTTP message from kb.com,
which contains
Hypertext Transfer Protocol
HTTP/1.0 200 OK\r\n
Request Version: HTTP/1.0
Response Code: 200
Server: QTSS/5.5 (Build/489; Platform/MacOSX; Release/Final; )\r\n
Connection: close\r\n
Date: Thu, 19 Aug 1982 18:30:00 GMT\r\n
Cache-Control: no-store\r\n
Pragma: no-cache\r\n
Content-Type: application/x-rtsp-tunnelled\r\n
\r\n
In acknowledgement flags should get set as below:
Flags: 0x0002 (SYN)
0... .... = Congestion Window Reduced (CWR): Not set
.0.. .... = ECN-Echo: Not set
..0. .... = Urgent: Not set
...0 .... = Acknowledgment: Not set
.... 0... = Push: Not set
.... .0.. = Reset: Not set
.... ..1. = Syn: Set
.... ...0 = Fin: Not set
Window size: 65535
Checksum: 0xc5c6 [correct]
Options: (12 bytes)
Maximum segment size: 1460 bytes
NOP
Window scale: 2 (multiply by 4)
NOP
NOP
SACK permitted
However it is getting set as
Flags: 0x0002 (SYN)
0... .... = Congestion Window Reduced (CWR): Not set
.0.. .... = ECN-Echo: Not set
..0. .... = Urgent: Not set
...1 .... = Acknowledgment: Set
.... 0... = Push: Not set
.... .0.. = Reset: Not set
.... ..0. = Syn: Not Set
.... ...0 = Fin: Not set
Window size: 6432
Checksum: 0xc864 [correct]
SEQ/ACK analysis
This is an ACK to the segment in frame 1557
The RTT to ACK the segment was: 0.000025000 seconds
Now my query is:
1. Whether squid support RTSP tunneling or not?
2. If it supports then what setting requires to handle RTSP tunneling.
