F5 iRule redirects to different pools, url with dynamic content and 404 answer

Question

I have a question, I can't get a success, I need an iRule to do the following:

We want to send a request that go to a specific host to be directed to a specific pool. So far that's not a problem

next, the requests from this host should then have dynamic content in the URI / firstname-lastname /

here is always the MINUS otherwise, I thought string-string or something but I didn't really find anything about such a scenario.

Is that possible ? And then of course that should also be in a certain pool, but when a 404 comes back then it should turn into

another pool. Maybe I could get some example or hints or some similar example. And what would be nice as well to mask the

redirects so that the user can't see it in the browser. I have never built such a scenario with iRules and I am usually never blessed

with success in iRules ; (. I would be happy to hear from someone.

Best regards

Manu

Your problem statement is not really clear, so it is hard to give you any good direction.

However, you can change pool and retry the request on a 404 response from the server side with the

command. Take a look at the example irule, which changes pool and retries on a 5xx response.
