HTTP_REFERER CGI Environment Variable Does Not Get Set Correctly In MOD_PLSQL (Doc ID 311669.1)

Last updated on JUNE 02, 2023

Applies to:

Oracle HTTP Server - Version 1.0.2 and later
Information in this document applies to any platform.

Symptoms

Oracle HTTP Server - Version: 3.0.0.4 to 3.0.0.7
This problem can occur on any platform.

- Migrating PL/SQL Web application from OAS 4.0.8.2 to HTTP Server that ships with the 8.1.7 database.
- The application makes use of HTTP_REFERER in order to determine where the user has come from for security reasons, i.e. owa_util.get_cgi_env('HTTP_REFERER').
- When running under 8.1.7 HTTP Server this parameter is not getting set thus the check made in the PL/SQL code fails to give the desired result.
- This worked correctly in OAS 4.0.8.2
