=head1 DESCRIPTION |
31
|
|
|
|
|
|
|
|
32
|
|
|
|
|
|
|
Net::WebSocket is agnostic as to which tools an implementor may use to parse |
33
|
|
|
|
|
|
|
HTTP headers. CPAN offers a number of options for doing this, and different |
34
|
|
|
|
|
|
|
applications may have varying reasons to prefer one or the other—or an |
35
|
|
|
|
|
|
|
entirely different approach altogether. |
36
|
|
|
|
|
|
|
|
37
|
|
|
|
|
|
|
This module provides convenient logic for the L and |
38
|
|
|
|
|
|
|
L CPAN modules. Any implementation that uses one of these |
39
|
|
|
|
|
|
|
modules (or a compatible implementation) can use Net::WebSocket::HTTP_R and |
40
|
|
|
|
|
|
|
save a bit of time. |
