source: greenstone3/trunk/web/WEB-INF/cgi/gliserver.pl@ 16427

Last change on this file since 16427 was 16427, checked in by ak19, 13 years ago

Reinstated the commenting out of a check for pre-existing directory. The lines were commented out in the gliserver.pl for GS2, but not that of GS3 and only cropped up once when running GS3 remote on Windowse so far
