Hi,

Apologies in advance for a fairly high level question which may not be the
norm of this users group.

I am trying to understand options and eventually choose a software load
balancer for a project I am working on. I am specifically interested in the
capabilities of two options - Apache HTTPD mod_proxy_balancer and Varnish (
<a href="https://www.varnish-cache.org/trac/wiki/LoadBalancing" title="https://www.varnish-cache.org/trac/wiki/LoadBalancing">https://www.varnish-cache.org/trac/wiki/LoadBalancing</a>) from the following
perspectives:

1. Feature set supported like - session stickyness, failover from one node
to another in the load balancer farm etc
2. Performance/throughput
3. Stability of the solution
4.

Hi,

I am looking for ways of detecting a specific mobile device (example: my
iPhone and not my friends) accessing a resource on my publicly accessible
Apache web server so that I can restrict access to certain devices only.

Just like there are ways of detecting the user agent and IP address of the
device where the request originates from and restricting access accordingly,
is there a way to do something similar for an iPhone for example, connected
to 3G network (not wifi)?

Any pointers towards this would be highly appreciated.

Regards
Anurag
