Message for authentication popup
Upon request the reverse proxy will ask for a login before it forwards requests to certain
backends. Only members of SX-GATE group "system-proxy" will be accepted. Web
browsers usually open a small popup windows, asking for login and password. Among
other things, the popup will display the message you enter here. It should indicate the
authentication's purpose to the user.
You should however avoid to draw the attention of criminals on
the system by being too specific.
Check syntax of requests
Enabling this option enhances the security. Every requested URL will be validated if it
complies with the standard. Access will be denied if the URL contains invalid characters
or the order of its components is not correct.
permissive
A lot of non standard-compliant characters will be accepted as part of an URL
when selecting this option. Choose it as a last resort if the more restrictive options
do not work for you. If access to the backend is still denied you will have to disable
the syntax check.
Microsoft optimized
Some violations of the standard have to be accepted to provide access to
Microsoft's Outlook Web App (OWA). Problems in very specific cases might occur
nevertheless.
strict
With this option, the verification conforms broadly to RFC2396.
Accept extended HTTP commands
By default only the HTTP methods "GET", "POST" and "HEAD" will be accepted by
the reverse proxy. Enable this option if "PUT" and all the WebDAV methods have to
be supported, too.
This option is required for access to Microsofts Outlook Web App
(OWA), Outlook Anywhere or a remotedesktop gateway.
