=head1 DESCRIPTION |
23
|
|
|
|
|
|
|
|
24
|
|
|
|
|
|
|
This backend uses L to make HTTP requests. |
25
|
|
|
|
|
|
|
|
26
|
|
|
|
|
|
|
L is a wrapper for L which is |
27
|
|
|
|
|
|
|
Pure-Perl only and doesn't require any architecture specific files. |
28
|
|
|
|
|
|
|
|
29
|
|
|
|
|
|
|
It is possible to bundle it e.g. by L. |
