Hi,
Someone suggests an idea of how I would prioritize requests ina webserver.
Requests with more priorities are processed first than less priorities.
I don't have any idea.
Thank You
Ricardo

Can you provide a practical example of what you're trying to achieve?
This sounds like a violation of net-neutrality, but anyway most web
requests shouldn't take longer than a second or two anyway so I don't
know what kind of performance boost your top-tier customers can
reasonably expect with regards to response time from apache.

Hi,
Imagine a queue with many requests for low priority (requests-low), after
arrive a request high priority (request-high).
Request-high is then processed first than others. Provide QoS (Quality of
Service)
Thank you

Hi,
That's the question. I dont have any idea.
I think rename the process (Ex: httpd-high and httpd-low), or add some
variable.
I dont know !!! Do you have any idea ???

If you have no idea how to prioritize the requests, then I doubt you'll
get much help. Prioritization of "requests" can happen in the router, a
load balancer or the actual webserver.
For instance, if requests from certain IP addresses have a higher
priority (for example) then one could implement QoS (Quality of Service) at
the router level (allow traffic through unimpeeded from priority IP
addresses, otherwise cap bandwidth/connections from non-priority IP
addresseswithout an idea of what you need to prioritize on you are wasting your
time [3].

That's my objective !! Implement QoS at application level.
I have a web cluster and I thought the frontend mark the requests to
priorize.

I don't know why, but for me it seems to be 'better' implement this through
a proxy... It's application level, and it solves the problem.
Implement a HTTP proxy which do it and be happy!

I would like implement it in Apache webserver, but dont know where I start.

Ok, but it seems to be too much more effort to do exactally the same

As has been pointed out already, this is a very complex requirement,
best handled by another component (ie, not the webserver). The HTTP RFC
doesn't consider request priority so what you want to do would require
extensive engineering. It is a major project that a skilled engineer
might spend weeks on.. I do not think you will solve it as a novice,
just asking questions on a list.
I'm also not convinced you have a real motivation for wanting this - do
you really have a case where clients are having to wait a long time for
a response? If so, there are other ways to approach the problem.
Rgds,
Owen Boyle
