I just pushed an update to the Metalink plugin for Apache Traffic server [1] The update fixes a segfault that was reported by Faysal Banna [2]
[1] https://cwiki.apache.org/confluence/display/TS/Metalink [2] https://github.com/jablko/dedup/issues/1 I pushed the updated plugin to GitHub (hopefully it will also be distributed with the next Traffic Server release). To build it, 1) download the updated metalink.cc file [3], 2) replace the plugins/experimental/metalink/metalink.cc file in your Traffic Server source tree with the updated file, 3) and rebuild Traffic Server by rerunning "make". [3] https://raw.github.com/jablko/dedup/master/metalink.cc Here is a real example of what this plugin does: If I download the latest version of LibreOffice, their download redirector (MirrorBrain) sends me to tdf.mirror.rafal.ca But if several users are all sitting behind Traffic Server and someone has already downloaded this file from mirror.nexcess.net, the response from MirrorBrain is rewritten to redirect me to that mirror instead. Then I will get the file that Traffic Server cached, instead of going out over our internet connection. Here is the response I get from MirrorBrain: $ curl -v download.documentfoundation.org/libreoffice/stable/4.2.0/rpm/x86/LibreOffice_4.2.0_Linux_x86_rpm.tar.gz > /dev/null < HTTP/1.1 302 Found < Link: <http://tdf.mirror.rafal.ca/libreoffice/stable/4.2.0/rpm/x86/LibreOffice_4.2.0_Linux_x86_rpm.tar.gz>; rel=duplicate; pri=1; geo=ca < Link: <http://mirror.nexcess.net/tdf/libreoffice/stable/4.2.0/rpm/x86/LibreOffice_4.2.0_Linux_x86_rpm.tar.gz>; rel=duplicate; pri=2; geo=us < Digest: SHA-256=YVJGdJtB7E2kxPTBjLPBwd4zhlgiDclzqBUTWyvzGkk= < Location: http://tdf.mirror.rafal.ca/libreoffice/stable/4.2.0/rpm/x86/LibreOffice_4.2.0_Linux_x86_rpm.tar.gz But if I cause the proxy to cache the file from mirror.nexcess.net ... $ curl -vx localhost:8080 mirror.nexcess.net/tdf/libreoffice/stable/4.2.0/rpm/x86/LibreOffice_4.2.0_Linux_x86_rpm.tar.gz > /dev/null ... then the proxy will rewrite the response from MirrorBrain: $ curl -vx localhost:8080 download.documentfoundation.org/libreoffice/stable/4.2.0/rpm/x86/LibreOffice_4.2.0_Linux_x86_rpm.tar.gz > /dev/null < HTTP/1.1 302 Found < Location: HTTP://mirror.nexcess.net/tdf/libreoffice/stable/4.2.0/rpm/x86/LibreOffice_4.2.0_Linux_x86_rpm.tar.gz And I will get the file that the proxy cached. I hope other people will find this useful. -- You received this message because you are subscribed to the Google Groups "Metalink Discussion" group.
