Questions regarding using the .monitor command to retur a animated image and we would like feedback to a designed webpage that is monitoring a 5kW windturbine:)

Question

I'm embedding a front panel image in an existing HTML dokument. I would like to use the command .monitor in the URL together with the refresh command so the VI automatic will reload every 20 secund. This actual work, but simultaneous I want to have the possibility to refresh manually so I don't have to wait 20 sec before new values is shown in the display. Is this possible to do?
Another question: Since the real time display updates 1-2 times a secund the command .monitor is used to get a animated picture of the Real Time Display.
There are several ways to add animation on to web pages. The techniques used h
ere are the �server push� and �client pull�which makes the browser repeatedly reloads a changing inline image to provide crude animated sequences. This is not the most efficient way as this result�s in an image being re-transmitted for each frame of the animation. The command .monitor with the attribute refresh and lifespan in the URL trigger this �server push� and �client pull� techniques.
I use this automatic refresh uploading of the display so that it each time shows different values, is this called crude animation?Then I'm wondering what I'm suppose to use the command lifespan to?I can't see the use of it in my display.....?
link to the webpage so you can have a look at the display:
http://134.7.139.176/.monitor?Real%20Time%20Performance.vi&refresh=20
This is a project that I'm working together with another Norwegian friend. WE are very happy for feedback on our web page and displays go to: http://www.ece.curtin.edu.au/~peersena/ if you would like to view itThanks

Annis,
One of the other things to keep in mind is that the generation of an image does take some computing power so having the generation and the acquistion on the same machine is not always ideal. If you're using the machine that is publishing the front panel just to collect data it's not so much of an issue.
If you really want to monitor in "Real-Time" using Remote Panels (requies LabVIEW 6.1) is your best option. This posting has more information on using Remote Panels and links to some live examples:

Remote panels makes it possible to control the application remotely as well.
With .monitor the only way I've been able to manually refresh is to "Shift+Refresh" on the browser.
