[[!template id=gitbranch branch=schmonz/proxy author="[[schmonz]]"]] [[!tag patch]] ## Background Ikiwiki has several plugins that open outbound connections: * [[plugins/aggregate]] * [[plugins/openid]] * [[plugins/pinger]] In some networks it is desired (or necessary) for these connections to traverse a proxy. Proxies are usually configured via environment variables, so for ikiwiki it is probably not desirable (or necessary) to manage proxy configuration via new purpose-specific settings in the setup file; `ENV` ought to suffice. [[!cpan LWP::UserAgent]] by default doesn't care about the usual environment variables, but if its constructor is passed a true `env_proxy` value, it does. Then environment settings such as these influence the agent, as expected: ENV: http_proxy: 'http://foo.internal:8080' no_proxy: 'localhost,.bar.internal' If the proxy and/or destination requires authentication, it may also be necessary to prime `cookiejar`. ## Changes This patch causes ikiwiki's `LWP::UserAgent` instances to: * honor proxy configuration in the environment * consistently make use of cookies configured in the setup file ## Limitations The patch lets me configure [[plugins/aggregate]] to traverse my corporate proxy and to skip the proxy for internal hosts. I haven't tested it with the other two plugins, both of which prefer [[!cpan LWPx::ParanoidAgent]] if present, which deliberately lacks proxy support. There exists [[!cpan LWP::UserAgent::Paranoid]] claiming to be more modern, but I haven't looked at it further, so I don't know whether its paranoia measures up or whether it supports proxies. ## See also * [[bugs/http_proxy_for_openid]] * [[forum/Setting_http__95__proxy]] > This looks fine, but you forgot to move the config entry for cookiejar > from aggregate to the config setting list in IkiWiki.pm --[[Joey]] >> Indeed, fixed. --[[schmonz]] >>> [[merged|done]] --[[Joey]]
