Different maintenance mode pages in multistore

[squatter]

Hello, 

I have following problem:

I have 3 shops in multistore, each on different domain. I have turned on maintenance mode on shops 1 and 2.

 

Now what I want:

 

shop 1 to show maintenance page and

 

shop 2 redirect to some other address.

 

How do I achieve that? Please help.

 

Thanks for your answers.
