Are you running BGP routing with ISP1 and ISP2 to your own IP space?
If not,
I would suspect an issue with your web server in how the pages are
being called in terms of IP address vs. domain name as something to look
into. Have you looked at your server's access logs and error logs?
Making a situation such as you have diagrammed work with BGP routing
is marginally on topic for this mailing list, which is concerned with
Cisco CCIE certification.
Making it work without BGP routing involves NAT which could also be
marginally on-topic, as well as some DNS hacks which are not. Your
approach should involve such things as the relative sizes of the pipes
to ISP1 and ISP2, whether you are looking for redundancy or failover,
and the clue-level of those who will be maintaining it.
You might be better off finding a good co-location facility that is
multi-homed, equipped with the environmental and backup power facilities
that you'll need for high-availability web sites, and which has clueful
people who can deal with the dirty work.

If such is the case, let me know off-list.

We now return you to our regular programming of flapping ISDN lines,
IPX tunneling, and bit-twisting MAC addresses between TR and ethernet.
