Persisting Data Across Redirects

[Nick]

Hey Guys,

Suppose you are are doing a redirect - let's say validation has failed
has failed so you want to go back to the GET action. You now need the
validation errors to be available.

What do you guys see as the best way to do this?

I can see:

+ IFlash
+ ISessionState
+ Serialize the validation errors in say a request header

With the first two options, what if my app is running across multiple
servers - does the redirect stay inside the same process or would it
be routed as per any other request to say a load balancer?

Cheers

Well a redirect is sent to the browser and the browser makes the request so it would be subject to your load balancers. A serverside transfer would avoid that. I am pretty sure Ryan has just felt with this problem and may have a good idea if no one else does.

Just a guess, but a memcached / asp.net cache backed IFlash would probably be the best, since you have some scale issues.

Cheers for the replies. That's basically what I though, just checking fubu didn't do something clever with redirects.

I think I'll just add the errors to the redirect request in the  most efficient - serialize the errors object or something with a smaller footprint.

As it happens I was being dumb anyway. Partials are what I wanted. I love the concept of partials though :)

Good post by your team here  http://www.dovetailsoftware.com/blogs/kmiller/archive/2012/04/24/fubumvc-hijacking-behaviors
