1: Server Down for Maintenance Page
Posted by Ryan Gallimore on 07/10/07 05:39 PM
How are people creating a "Down for Maintenance Page" when upgrading their site?

I'd like an easy way to turn on and off redirection to a "Down for Maintenance" notice page. Any suggestions?

Thanks.

Hi Ryan,

One way is to register a filter proc which, when called, redirects all requests to a "Down for maintenance" page. Then have a special admin page that turns on or off that proc.

An even easier way is to have a second tcl initialisation files for AOLserver - which just points to a "Down for maintenance" page.

Hi Brian,

Is there a way to redirect all requests via filter proc except the one to the maintenance page? Won't this require a request on the login page and therefore defeat the purpose of the redirect?

Thanks.

Sure, in the registered proc, make an exception for that URL.
A very old example here:

Re the login page, I'm honestly not sure how that'll work. Try it and see!
