## Step 6 Setting the http_proxy Environment Variable

The Notification Mailer is now capable of fetching the URL content of a URL attribute, if the attribute has Attach Content checked in its Attribute property page. If the referenced URL is outside your organization's firewall, the Notification Mailer must go through your organization's proxy server to fetch the URL content. Before starting your Oracle Workflow Database and the Notification Mailer, set up an environment variable called http_proxy to point to your proxy server.

For example, in UNIX, use the following command to set http_proxy to a proxy server called www-proxy.yourcompany.com:80:

    setenv http_proxy "http://www-proxy.yourcompany.com:80/"

If your Oracle Workflow database is a remote database, edit your Oracle Net8 listener.ora file to include the http_proxy environment variable in your SID description. For example, in the following SID description, http_proxy is set to `www-proxy.yourcompany.com:80:`

    (SID_DESC=

    	(SID_NAME=V817)

    	(ORACLE_HOME=/oracle/app/oracle/product/8.1.7)

    	(ENVS='http_proxy=www-proxy.yourcompany.com:80')

    )

Context: You need to perform this step only once.
