I want to write a server application that would accept HTTP requests from client.
The server would be on a machine that has no connection to the INTERNET.
The clients that would be posting their HTTP requests would be doing so through webbrowser .Thus it would be sort of intranet application.
While doing the homework for the same I am faced with few queries
1> As I gathered from couple of Internet references it seems that port 80,8080 are the two ports that I can utilise for this.
So to look up for whether these are free on the UNIX machine(SunOS ompmum4 5.9 Generic_117171-02 sun4u sparc SUNW,Ultra-60) i put "netstat-a" .
It showed me
ompmum4 rchakra> netstat -a|grep 80

============
From this I get a notion that port 80 is free perhaps.
But I have a problem...
To write server codes for port 80 I would need a root password which I do't have.
Also port 8080 is already taken it seems.
So I was left with a question...
Can I use any other unused port for this ...
Given the fact that this HTTP application will never be utilised outside the intranet I have a strong notion that this can be done.
Could anyone pl guide me with your advice.
