source: gsdl/trunk/cgi-bin/gliserver.pl@ 19189

Last change on this file since 19189 was 19189, checked in by ak19, 12 years ago
  1. Changes made together with related changes in gliserver.pl for making the DownloadPane available in the remote client-gli. DownloadInfo.pl is called and gliserver now expects a downloader argument with the name of the downloader. 2. Variable client_lang now renamed to lang_env and some changes to tidy this up. More importantly, when lang_env is the empty string (signifying that the LANG env var on the client side was not set and the Java zip tools were run in that environment) this empty LANG environment is reused by the server to run the ziptools as well, to ensure consistency in this special case.
