Web Server Demo Program

[Mike Siers]

Hi,
I hacked the c/src/libmisc/untar/untar.c file to remove
the blank characters from the string compare.  Now when
I step through the untar function it seems like everything
works.  

The web server comes up now since it reads the /etc/hosts 
file but I can not see the web page from my browser.  The
RTEMS box accepts the HTTP request but my browser is getting 
back a 400 page not found error.

Any more hints?

According to the OpenGroup tar.h specification, TMAGIC is "ustar"
which is "ustar plus null byte".  So I think it is incorrect to
assume that the space is there.  TMAGLEN is 6 as the length of 
TMAGIC.    The standard is online so you can read it yourself.

This is normal from my experience.
