Pound was developed to enable distributing the load among several Web-servers and to allow for a convenient SSL wrapper for those Web servers that do not offer it natively. Pound is distributed under the GPL &#8211; no warranty, it&#8217;s free to use, copy and give away.<br \/>\n<strong>WHAT POUND IS:<\/strong><\/p>\n<p>   1. a reverse-proxy: it passes requests from client browsers to one or more back-end servers.<br \/>\n   2. a load balancer: it will distribute the requests from the client browsers among several back-end servers, while keeping session information.<br \/>\n   3. an SSL wrapper: Pound will decrypt HTTPS requests from client browsers and pass them as plain HTTP to the back-end servers.<br \/>\n   4. an HTTP\/HTTPS sanitizer: Pound will verify requests for correctness and accept only well-formed ones.<br \/>\n   5. a fail over-server: should a back-end server fail, Pound will take note of the fact and stop passing requests to it until it recovers.<br \/>\n   6. a request redirector: requests may be distributed among servers according to the requested URL.<\/p>\n<p>Pound is a very small program, easily audited for security problems. It can run as setuid\/setgid and\/or in a chroot jail. Pound does not access the hard-disk at all (except for reading the certificate file on start, if required) and should thus pose no security threat to any machine.<br \/>\n<strong>WHAT POUND IS NOT:<\/strong><\/p>\n<p>   1. Pound is not a Web server: by itself, Pound serves no content &#8211; it contacts the back-end server(s) for that purpose.<br \/>\n   2. Pound is not a Web accelerator: no caching is done &#8211; every request is passed &#8220;as is&#8221; to a back-end server.<\/p>\n<p><a href=\"http:\/\/www.apsis.ch\/pound\/\">http:\/\/www.apsis.ch\/pound\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Pound program is a reverse proxy, load balancer and [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_crdt_document":"","footnotes":""},"categories":[],"tags":[],"class_list":["post-890","post","type-post","status-publish","format-standard","hentry"],"_links":{"self":[{"href":"https:\/\/www.mudone.com\/index.php?rest_route=\/wp\/v2\/posts\/890","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.mudone.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.mudone.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.mudone.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.mudone.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=890"}],"version-history":[{"count":0,"href":"https:\/\/www.mudone.com\/index.php?rest_route=\/wp\/v2\/posts\/890\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.mudone.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=890"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.mudone.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=890"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.mudone.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=890"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
