Hi Simon, Thanks for your reply.
I am looking to achieve the solution within our existing infrastructure and without performing much changes to the current application deployment. I was trialling with "first_byte_timeout" which if reached will fall into "vcl_error" and then serving a busy page from there. However there are certain hurdles (how to distinguish a new user with existing and other things that I have not been able to think of) Is there anything in this regard that you or someone may have done ? Thanks Roy N. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Simon Lyall Sent: Monday, 19 November 2012 9:17 AM To: [email protected] Subject: Re: Limiting users to the website On Mon, 19 Nov 2012, Narayan, Roy wrote: > I am looking to limit users to the website once we hit capacity.

Give everybody a short-lived cookie. If they have the cookie then serve them pages as normal. "New" users won't have the cookie, so make the use a different backend and make that backend "fail first" with a pretty error page. -- Simon Lyall | Very Busy | Web: http://www.darkmere.gen.nz/ "To stay awake all night adds a day to your life" - Stilgar | eMT. ************************************************************************************************ DISCLAIMER Confidential Communication: This email and any attachments are intended for the addressee(s) only and are confidential.
