different LAN that the Browser ?

Today is my very first experience with the UltiDev Cassini. As first try I used simple html file with "Hallo world" message as my application. From Web browser being on the same LAN as Cassini application there was no problem. But when trying to access this application from browser outside the Cassini LAN - failure.

Andrew,

This is most likely to be a routing issue. Can you ping a destination machine? UltiDev Cassini does handles all requests it receives regardless where they come from.

Hi,

Case_1: Browser and application are now on the same LAN. Interesting thing is that the browser displays my html page, but pinging the server machine fails.

Andrew,

We strongly believe that this is a networking/routing issue. If you have reasons to believe that it's a Cassini-specific issue, could you please provide additional details, like, maybe, you have IIS on the same machine, and IIS is reachable while Cassini is not.

Hi guys,

My Cassini machine does not have IIS installed.

From the web browser I'm using the following format of url address to display my page:

http://111.222.333.444:3000/MyPage.html

When the browser machine is in the same intranet as Cassini the page displays as expected.
When the browser machine is outside Cassini machine intranet my page DOES NOT display.

Regards, Andrew_3O

Andrew,

Unfortunately we won't be able to troubleshoot this knowing only that from Cassini is unreachable from another network. If this is a networking/routing issue, and we think it is, we have no way of knowing what can be wrong. We can help with most of Cassini-specific problems, and with lots of ASP.NET-related issues, but networking and routing is something that should be addressed before we can step up. We recommend installing some other TCP server application on the same box and try to reach it from another network, to find out whether this is a networking issue or Cassini issue. For example, if your OS is XP Pro, then you can install IIS and see if you can reach it from outside network.

Hello

I did the following sequence:

1. With Cassini service turned off I activated my Java server on the Cassini machine. Now regardless where the browser is (inside or outside Cassini machine intranet) the browser properly displays my html page.

2. Turned off Java server. Tried to activate Cassini Web Server Explorer - got error message saying something that page cannot be displayed.

3. Had to activate "Restart Casiini for ASP.NET 2.0 Service"

4. Registered my application (html page) with Cassini sevrer.

5. Now ONLY the browser inside Cassini intranet properly displays my page and the other browser fails.


Sorry guys for bugging you with my problem but doesn't that case deserve solving ????

Regards, Andrew

Andrew,

Thank you for providing additional details. Being bugged is no problem - we want make our software as bug-less as possible. Since other web server was reachable while ours was not, we'll definitely try to find out what's going on, even though this is the first time we have come across this issue.

We would like you to install Fiddler http tracer on both client boxes - inside and outside the network, and trace the HTTP requests in both cases and see if you get any response at all from the Cassini. We would like to know what causes the error: no connection or HTTP response other than 200.

Also, what kind of OS is that? Is it XP Home, XP Pro, Vista Home?

In may setup there are 3 machines: cassini server (Windows XP home) and two clients:

1: Cassini server machine runs under Windows XP (home edition)
Client machines:
2.1: Windows 2000 - in the same workgroup as cassini server
2.2: Windows XP (home edition) - remote machine far outside the workgroup


To displaye may web page from server I use the same url address from both clients: http://131.137.69.19:2115/Page1.html

Installed the Fiddler software on both clients. Client 2.1 displays my html page as expected. But when tried to display the page from 2.2 client got the following response from the fiddler:

[Fiddler] Connection to 131.137.69.19 failed.
Exception Text: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

Hello

As I have mentioned before my browser displayed my page properly when the web server was a Java program. Now also a different server downloaded from: http://www.uniformserver.com/ performs normally, like the Java one.

Now things are even more interesting why your Cassini server still refuses to work, aren't they ?

Andrew,

Those other servers that work, do any of them use non-standard ports outside of usual http port 80? Is it possible that there is a firewall somewhere between the second client and the server that blocks port 2115? Would it be possible to run a Java server or other web server on a non-standard port and see if they are still accessible from the client #2?

With Java server both clients display page OK only when this server uses port 80.

I also tried to assign port 80 to the Cassini. In this case only client 2.1 (same workgroup as Cassini) displayed page OK even without specifying port number in the url address box. Client 2.2 failed.

Again, so far the client 2.2 displayed page OK only with server being a Java one and being on port 80.

Thanks UltiDev Team for your cooperation. Who knows maybe we'll resolve this issue somehow.
Regards, Andrew.

We wish we could be more helpful. It's pretty clear something's going on with networking/routing/firewall settings.

Please let us know if we could be of more help.
