HTTP::Cache::Transparent is an implementation of http get that keeps a local cache of fetched pages to avoid fetching the same data from the server if it hasn't been updated. The cache is stored on disk and is thus persistent between invocations. The http-headers If-Modified-Since and ETag are used to let the server decide if the version in the cache is up-to-date or not.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
