Rewriter depends on the MIME type of the page to choose the parser. Some web servers such as WebLogic and Oracle do not send MIME types. To work around this, you can enable the MIME guessing feature by adding data to the Map Parser to URIs list box.
Type the following command and press Enter to manage MIME guessing.
To enable MIME guessing:
PS_INSTALL_DIR/bin/psadmin set-attribute -u amadmin -f PASSWORD_FILE -m gateway --gateway-profile PROFILE_NAME -a EnableMIMEGuessing true
To disable MIME guessing:
PS_INSTALL_DIR/bin/psadmin set-attribute -u amadmin -f PASSWORD_FILE -m gateway --gateway-profile PROFILE_NAME -a EnableMIMEGuessing false
To get value:
PS_INSTALL_DIR/bin/psadmin get-attribute -u amadmin -f PASSWORD_FILE -m gateway --gateway-profile PROFILE_NAME -a EnableMIMEGuessing
