Try removing the trailing slash on this line.

How these pages (home, login, and signup) are looked from rails side ?  
What their URLs ?

the url’s are redirected to main/home in the rails apps side…

The problem now is that

The things which are redirected to main /home gets directed to

[http://domain.com/main/home](http://domain.com/main/home)

I want it to be redirected to

[http://domain.com/app1/](http://domain.com/app1/)

how do i redirect it using nginx???

I do not understand the question.  
I do not know typical rails URLs.  
Could you write how should the URLs be mapped ?  
For example,

```
   outside world: Rails:

 domain.com/app1/ > www.domain.com/main/home
 domain.com/app1/login > www.domain.com/main/login

 domain.com/app2/ > www.domain.com/main2/home

 domain.com/app3/ > www.domain.com/main3/home

```

the redirecting should be as follows:

outside world: Rails:

[domain.com/app1/](http://domain.com/app1/) \> [www.domain.com/app1/main/home](http://www.domain.com/app1/main/home)  
[domain.com/app1/account/login](http://domain.com/app1/account/login) \>  
[www.domain.com/app1/account/login](http://www.domain.com/app1/account/login)  
after logging in should be redirected to \> [www.domain.com/app1/](http://www.domain.com/app1/)

[domain.com/app2](http://domain.com/app2) \> [www.domain.com/app2/main/home](http://www.domain.com/app2/main/home)

[domain.com/app3](http://domain.com/app3) \> [www.domain.com/app3/main/home](http://www.domain.com/app3/main/home)

i hope u’r able to understand from the above example.

Figured this out from another post…  
you have to use the prefix option for mongrel which can be called on the  
command line of included in the .yaml file in /etc/mongrel (if you have  
it configured that way)

See: [http://mongrel.rubyforge.org/wiki/FAQ](http://mongrel.rubyforge.org/wiki/FAQ)

I am having the same exact issue that you describe… did you ever  
figure out a solution?
