HTTP::Tiny::Patch::Cache - Cache HTTP::Tiny responses
This document describes version 0.004 of HTTP::Tiny::Patch::Cache (from Perl distribution HTTP-Tiny-Patch-Cache), released on 2019-04-14.
use HTTP::Tiny::Patch::Cache # -max_age => 7200, # optional, sets max age, can also be set via environment variables ; my $res = HTTP::Tiny->new->get("http://www.example.com/"); my $res2 = HTTP::Tiny->request(GET => "http://www.example.com/"); # cached response
From command-line (one-liner):
% perl -MHTTP::Tiny::Patch::Cache -E'my $res = HTTP::Tiny->new->get("..."); ...'
To customize cache period (default is one day, the example below sets it to 2 hours):
% CACHE_MAX_AGE=7200 perl -MHTTP::Tiny::Patch::Cache ...
To clear cache, you can temporarily set cache period to 0:
% CACHE_MAX_AGE=0 perl -MHTTP::Tiny::Patch::Cache ...
Or you can delete $tempdir/http_tiny_patch_cache/, where $tempdir is retrieved from File::Util::Tempdir's
This module patches HTTP::Tiny to cache responses.
Currently only GET requests are cached. Cache are keyed by SHA256-hex(URL). Error responses are also cached. Currently no cache-related HTTP request or response headers (e.g.
Cache-Control) are respected. This patch is mostly useful when testing (e.g. saving bandwidth when repeatedly getting huge HTTP pages).
Int. Sets maximum age for cache. If not set, will consult environment variables (see "ENVIRONMENT"). If all environment variables are not set, will use the default 86400.
Int. Will be consulted after "HTTP_TINY_PATCH_CACHE_MAX_AGE".
Int. Will be consulted before "CACHE_MAX_AGE".
