1 URL of output 2 poll of balance

I would like to know Which type of request is more efficient as iRules

I have a URL that I can enter, for example: www.company.com/page/service

I have the same balanced across two pools pool_company1 /page/service pool_company2 /page2/service

Note that the destination URL differs for both nodes

And when you want to balance, always show the URL www.company.com/page/service

by more than swing through /page/service or /page2/service
