RE: TiniHttpServer and GPRS or Tynamo?

Dear Manual - Re: "I can talk about IWS, www.servertec.com, and I imagine
the others work the same.".

>From what I have been available to "generally demonstrate" to myself,
without some very firm benchmark numbers, is that the current "incarnation"
of Tynamo is about three times faster than SSC's (Dave McMahon's)
TiniHttpServer.  I have not tried to compare to IWS from Servertec (You!)
lately, but I would like to invite you to compare Tynamo with IWS, and give
us all some "real numbers".  I am just not sure, as to how about going
aboutmyslf (ie., to benchmark a TINI server).  It might (or might not) have
some marketing advantage for you and Shawn Silverman, to give us all some
benchmarks to go by (and "Go Buy!).

I invite your thoughts on this subject.  Best regards, Kelly Smith

P.S. I use the Dalsemi 390 (Rev. D, 1 MB), and Systronix TStik 400 (1 MB),
as far as hardware platforms.  And yes, I still have my licensed copy of IWS
from you (about 3 years back)!  8D

Hello,

While I cannot talk about TiniHttpServer nor Tynamo, I can talk about IWS,
www.servertec.com, and I imagine the others work the same. Normally when we
ship IWS it is configured to listen for requests on port 8080 and not 80.
This can easily be changed by setting port=80 in iws.ini configuration file
as documented. Port 80 is normally the port used by Web servers and port
8080 is normally used by Servlet engines. Please be aware that IWS is both a
Web server and Servlet engine.

IWS does not open any socket ports we only open a server socket port to
listen for requests. When a requests comes in we use the input stream and
output stream of the socket we get from the server socket. As far as I know
if you have a firewall you will only need to open the port that we are
listening on. Finally you may need to open other ports for things like DHCP.

Using IWS with PPP is simple, just setup PPP and then start IWS. When
requests come in it is transparent to IWS. It thinks that the request and
response are going over TCP/IP Ethernet. The magic is done by the PPP
software.

I have noticed that if PPP is not properly setup the TCP/IP stack may not be
properly setup and then IWS will not get the requests. To check do an
ipconfig and verify that you have an IP address and that things are
configured properly, then configure IWS to log access, events and errors in
logger.ini file, then start IWS finally make and requests and lookout for
logger entries to console.

Good luck and please let me know how it goes.

Manny
