Hi, Please can you tell me, if it is possible with Nevow (does it require LivePage as well?) to force all browsers which are viewing a web page to reload their contents if the server changes this page? I.e., to force a browser to immediately refresh the page whenever it is changed on server. Non-regularly. E.g. live statistics - a server collects data and visualize them by an image. Everytime it gets something new, it re-creates the image. And I would like that every user currently being on this page will see the change immediately. I'll be glad for any help, hint, tip, strategy, ... Thank you very much.

It _requires_ LiveEvil. Just use mind.sendScript("window.location.reload();") then. -- Sridhar R - http://cs.annauniv.edu/~rsridhar Blog: http://www.livejournal.com/~sridharinfinity

The above is correct although refreshing the whole page may be like taking an axe to the problem. Sridhar, I mean no offence by that - you answered the question that was asked. LiveEvil is far too cool to be used to refresh the whole page ;-). LiveEvil actually allows you to update specific parts of the page; the rest of the page is left unchanged. That tends to produce a much better user experience as there is less "flicker" on the page. The main demonstration of LiveEvil is chatola - included in the Nevow releases (latest is 0.3). Another LiveEvil example is the incredibly dull itsalive (.tac and .html) in sandbox/mg (available in the Nevow SVN repository). Hope this help.

I agree. But it must not be used for any large markup modifications. Other side-effects are difficult to save HTML to disk (at least any mozilla plugin for this - save html from DOM) -- Sridhar R - http://cs.annauniv.edu/~rsridhar Blog: http://www.livejournal.com/~sridharinfinity
