Redirect / but send to pool if /abc/123.aspx in URL

After doing more research, I thought I would try to explain it better. I would like to redirect everything to except one URL, and I want to be able to get through to the pool.

So something like this.

Redirect everything for odi.domain.com (http and https) to except if https://odi.domain.com/abs/123.aspx is called, and then I dont want to redirect it. I want to allow it through to the pool. Is this possible? Anyone? Anyone? Bueller.... Bueller....

Thanks.
