s.
Name | Meaning |
---|---|
maxInitialLineLength |
The maximum length of the initial line
(e.g. "SETUP / RTSP/1.0" or "RTSP/1.0 200 OK" )
If the length of the initial line exceeds this value, a
TooLongFrameException will be raised. |
maxHeaderSize |
The maximum length of all headers. If the sum of the length of each
header exceeds this value, a TooLongFrameException will be raised. |
maxContentLength |
The maximum length of the content. If the content length exceeds this
value, a TooLongFrameException will be raised. |
