rtmphostlocal usage (because firewall workaround)

[szimszon]

Hi!

I have a weird problem. I was almost able to work around the firewall
problems (only 80 port).

But after I specified the rtmphostlocal value this value is used for
the http-servlet address too.
I have problem with file upload and download.

The url is: http://<rtmphostlocal>:<red5httpport>/...
but I need: http://<the address in the browsers address bar>/...

I think it could be good to have one another field called
httphostlocal and httphostlocalport or so to do the job :)

In my situation:

* I have 1 IP address, one computer
* I use apache2 to proxy everything
<VirtualHost 212.52.166.158:80>
ServerName meet.oregpreshaz.eu
AddDefaultCharset UTF-8
ProxyPass / http://localhost:5080/openmeetings/
ProxyPassReverse / http://localhost:5080/openmeetings/
<Proxy *>
Allow from all
</Proxy>
ErrorLog /var/log/apache2/meet.oregpreshaz.eu/error.log
CustomLog /var/log/apache2/meet.oregpreshaz.eu/access.log combined
</VirtualHost>

<VirtualHost 212.52.166.158:80>
ServerName rtmpt.oregpreshaz.eu
AddDefaultCharset UTF-8
ProxyPass / http://localhost:8088/
ProxyPassReverse / http://localhost:8088/
<Proxy *>
Allow from all
</Proxy>
ErrorLog /var/log/apache2/meet.oregpreshaz.eu/error.log
CustomLog /var/log/apache2/meet.oregpreshaz.eu/access.log combined
</VirtualHost>

* I use virtualhosts to separate http and rtmpt traffic
<rtmphostlocal>rtmpt.oregpreshaz.eu</rtmphostlocal>
<rtmpport>1935</rtmpport>
<rtmpTunnelport>80</rtmpTunnelport>
<red5httpport>5080</red5httpport>

But I need that the http domain name stay meet.oregpreshaz.eu and
_not_ the rtmphostlocal value rtmpt.oregpreshaz.eu

Is it possible to change the code to do the trick? After that you need
only port 80 to operate :) (I think:)

*http://<the address in the browsers address bar>*

=> if you leave the field *rtmphostlocal* blank it will automatically parse and use the URL (Domain) from Browser Bar (The URL the SWF has been loaded from)

Yes I know but I need two different domain name to operate two
channels (http and rtmpt) on the same port so apache2 can separate it
on virtualhost basis.

So I need
meet.oregpreshaz.eu[:80] for http-servlet
and
rtmpt.oregpreshaz.eu[:80] for rtmpt session

:(

I forgot I have red5 running on 5080 and rtmpt on 8088 standard ports
so apache2 do the proxy things

browser -> (meet.oregpreshaz.eu) http-servlet port 80 -> apache2 proxy
to localhost -> red5 port 5080
browser -> (rtmpt.oregpreshaz.eu) rtmpt port 80 -> apache2 proxy to
localhost -> rtmpt port 8088

[Sebastian Wagner]

this is not a recommended approach to run both applications on the same port.
You can use apache_proxy to make rtmpt and apache lookalike running both on port 80.

Yes, but it works partially (login and chat at least) . And I have to
run it on one port to be able to connect behind the firewall...

That is not the problem. The problem is that the code somewhere told
the browser for file download/upload to use "rtmpthostlocal value" and
"red5httpport" instead of the address in browser addressbar.

Sorry my English is not really good... :(

[Sebastian Wagner]

yes cause the *rtmpthostlocal* == red5 hostname.
You are right that this could be run on different host but for you its just a matter of different domain names.
*I have to
run it on one port to be able to connect behind the firewall*
=> if you use the apache_proxy modus it does LOOKLIKE running on one port cause apache rewrites internal everything from 80 to your rtmpt port.

It seems to me that the problem occur only on file upload/ download...

If I understand well if the OpenMeeting code say explicitly that the
browser must look for the file on <rtmpthostlocal>:<red5httpport> the
apache proxy could do nothing about it...

Could we possibly meet next week or so on skype/jabber/OpenMeetings to
discuss my problem if you have time?

I think I wasn't as precise on problem description as I wished :(
