Re: Calling CGI Programs in Apache Server

[Scott Klement <web400@xxxxxxxxxxxxxxxx>]

Hi Don,

The call to your CGI program is going to be based on the library in the 
URL, not the library list.  In other words, Apache is doing a CHGLIBL to 
set the library list you provide, but then is doing a CALL 
CGILIB/YOURPGM.   So the LIBL has no effect on which program is called.

Here's what I do:

ScriptAlias /cgilib /qsys.lib/CGILIB.LIB
<Directory /qsys.lib/CGILIB.LIB>
   Order Deny,Allow
   SetEnv QIBM_CGI_LIBRARY_LIST "QTEMP;CGILIB;QGPL;BLAH;BLAH;BLAH"
</Directory>

ScriptAlias /testlib /qsys.lib/TESTLIB.LIB
<Directory /qsys.lib/TESTLIB.LIB>
   Order Deny,Allow
   SetEnv QIBM_CGI_LIBRARY_LIST "QTEMP;TESTLIB;QGPL;BLAH;BLAH;BLAH"
</Directory>

The point being...   if the URL contains /cgilib, it'll call my 
production program, and if the URL contains /testlib, it'll call my test 
copy.  The library list for the test copy does not contain the 
production library (or vice-versa) since I discovered years ago that it 
was too easy to make mistakes that way.

Granted, if you have a lot of libraries, it might seem cumbersome to add 
them all to the Apache config like this.  In our case, we have one test 
lib per developer, and we have only 3 developers, so it's not a big deal.
