=head1 DESCRIPTION |
50
|
|
|
|
|
|
|
|
51
|
|
|
|
|
|
|
This module performs an HTTP request exactly the same |
52
|
|
|
|
|
|
|
as B does normally except for the fact that it |
53
|
|
|
|
|
|
|
times each stage of the request and then inserts the |
54
|
|
|
|
|
|
|
results as header. |
55
|
|
|
|
|
|
|
|
56
|
|
|
|
|
|
|
It's useful for debugging where abouts in a connection slow downs |
57
|
|
|
|
|
|
|
are occuring. |

has to smuggle the data back via a global variable. |

Based entirely on work by David Carter - |
91
|
|
|
|
|
|
|
this module is a little light frobbing and some packaging of |
92
|
|
|
|
|
|
|
code he posted to the libwww-perl mailing list in response to |
93
|
|
|
|
|
|
|
one of my questions. |
94
|
|
|
|
|
|
|
|
95
|
|
|
|
|
|
|
His code was, in turn, based on B by |
96
|
|
|
|
|
|
|
Gisle Aas which is distributed as part of the B package. |
