[ale] Sync apache module

[Chris Fowler]

I'm looking for a method to open a TCP connection to apache (80/443) and 
then issue a GET request that will execute a module that facilitates 
real-time sync communication.  Like ssh, telnet, etc.  I've been using 
proxy code that I've written, but with the state of companies locking 
down firewalls it would be easier if I could go back to the source 
instead of a different port.    I am tired of asking them to open up 
_another_ port to my server.

I guess this would kinda be like SOCKS.  I want to do this from the 
outside and the inside of the network!!!

I'll give you an example.  I have a device at a remote site that will 
create a TCP connect back to me server on port XXXX.  To get this to 
work I usually have to get their firewall staff to allow my device an 
outbound connection back to my server.  Now, these folks typically allow 
80/443 out.  If I can connect back to those it will make it easier.

Now on my own stuff (company owned) I have resorted to burning up an 
extra public IP and simply using NAT to redirect 80 -> XXXX.  This works 
great for me.  I can not ask my customers who also run this stuff to 
burn up theirs.   I've dealt with embedded type devices that used Java 
clients to do real-time stuff.  Specifically KVM over IP.  The devices I 
tested almost always connected back to their source.  Either 80 or 443. 
  The same port as their web server.

I'm thinking this problem has been solved and modification of Apache is 
the last thing I want to do.
