Back in Action

Finally starting this blog back up. Cody and I have greatly expanded our knowledge base on Oracle products and are excited about continuing to blog what we find out. Hope you enjoy... and maybe we will see you at OOW

Using CGI Environment Variable in APEX

If you execute the following in SQL Workshop of APEX you will get a list of the variables that are available for use.

begin
OWA_UTIL.PRINT_CGI_ENV;
end;

This will return:

SCRIPT_NAME = /apex

REMOTE_HOST =

REMOTE_ADDR = 10.26.0.97

SERVER_PROTOCOL = HTTP/1.1

REQUEST_PROTOCOL = HTTP

REMOTE_USER = ANONYMOUS

PATH_ALIAS =

REQUEST_CHARSET = AL32UTF8

REQUEST_IANA_CHARSET = UTF-8

SCRIPT_PREFIX =

This can now be used with owa_util.get_cgi_env() for validations on these items.
