url redirection LTM

Hi Experts,

I have one requirement in which application on server making a http call and F5 needs to convert that call to different URL. based on my understanding in basic browser based redirection, if someone type http or https URL, F5 can redirect them saying go to www. site instead and it's up to browser or client machines to resolve IP and reach out to redirection site. but what if client application make a call (not using browser) and client cannot resolve DNS for internet based URLs, how F5 can do that on behalf of client. kind of proxy setup I think?

Thanks
