[users@httpd] how to get httpd to use a proxy, cascading to a 2nd proxy ?
Hi all on users@httpd.apache.org
Can httpd _use_ (not just _be_) a proxy, cascading to a 2nd proxy on a gate ?
(Not just the common case of httpd serving as a proxy for down stream clients,
though I need that too on same httpd, I already have that part working)
I want to get httpd on an internal host to serve as a proxy to a
USB tethered android (which it is already doing), + to pass requests
over ethernet LAN to a 2nd proxy on a LAN gateway.
This may seem unusual, here's the reason:
An android is tethered (IP over USB) to a FreeBSD PC laptop,
Orweb browser on Android allows use of a proxy, FreeBSD
laptop runs apache 2.2.29 httpd (listening on the USB IP)
with httpd proxy enabled & PC allows android to reach various httpd PCs
on local LAN of the PC.
I now want to tell the httpd on the PC interfacing the android,
to pass android requests to a 2nd httpd running on the gateway host,
to reach the internet.
Why ? Why dont I just configure the FreeBSD PC to bridge packets
from USB to LAN ethernet, & on to LAN gate ?
- I may later want a firewall on the laptop ( to protect LAN from lots of
untrusted android binaries, + android WLAN & SIM interfaces).
- Pragmaticaly , I've tried & failed to create a bridge,
I think the FreeBSD PC side is OK:
/etc/rc.conf gateway_enable="YES" +
sysctl net.inet.ip.forwarding=1
But Android rejects syntaxes such as
route add default 192.168.42.139
route add default gw 192.168.42.139
route add default gw 192.168.42.139 dev eth0
& no manuals, & I'm new to Android (but familiar with Apache & FreeBSD)
If httpd wont use a proxy, maybe I'll try packet diversion
via FreeBSD's ipfw, but I'm hoping Apache httpd can use a proxy ?
I've read
http://httpd.apache.org/docs/2.2/urlmapping.html#proxy
& contemplated nasty cludges eg:
1st httpd on PC connected to android:
<VirtualHost *>
ServerName play.google.com
Redirect temp /store/apps http://gate/playgoogle
2nd httpd on LAN gate:
Redirect temp /playgoogle http://play.google.com/store/apps
But it would be Ugly & wouldnt work for other URLs, eg when android map apps
go other places to load maps etc.
Maybe there's some clever mapping with
http://httpd.apache.org/docs/2.2/rewrite/
1st httpd to be receive request
http://domain/url_under_domain
& emit
http://gate/indirect_trigger/domain/url_under_domain
& 2nd=gate to redirect to
http://domain/url_under_domain
Ideas / suggestions please ?
Cheers,
Julian

I am sorry but I can't
Answer your question cause I am still building my network but had to say
your setup sounds very interesting and I have similar plans with the
Android I am new to servers I installed Apache on a ubuntu host on a hp 8
gig ram installed on a 2 tb external hard drive I don't know much of the
command line so trying out windows server 2012 for the gui well this is
getting long and not pertaining to Apache so that said I'll end hear I'll
be studying your question in the future I am sure thanks for asking it
sorry I was of no help
