source: main/trunk/greenstone2/cgi-bin/gliserver.pl@ 22471

Last change on this file since 22471 was 22471, checked in by ak19, 14 years ago

Changes to get collectgroup working with a Remote Greenstone server on Windows: get script options is to launch a script with arguments, one of which is the collection again, which can be a collectgroup. GLI passes the collection name in with a verticalbar separating the colgroup from the coltailname. The safe_val method called on the arguments to the script doesn't preserve backslashes and vertical bars, so the vertical bar is first replaced with a forward slash, then the safe_val method is called before the forward slash is replaced with the OS's File separator slash.
