Hello Satya,

I think the formally it is simple to reply your

> May be by installing some plugins in the remote PC). Is it possible?

Yes, it is possible. The plug-in in question is called "root.exe". As soon as you install ROOT as Web browser plug-in to treat the files with "C" and "root" extensions, you can use the URL-link pointing to some ROOT macro/ ROOT file to start the "plug-in". (Please, pay your attention you may customize the local "ROOT Web plugin" behavior by tailoring "system.rootrc" file)

The only problem, that plug-in will NOT open its graphical window within the Web browser frame. The later can be fixed if crucial.

Is it the kind of things you keep in mind?

If your question is kind of "how to read ROOT file with no ROOT?" then this matter was discussed many times (search Web) in past and the bottom line was "one does need ROOT" always.

Best Regards

Hello Rene,

>>root > TFile *f = TFile::Open("http://root.cern.ch/files >>/pippa.root");

 I know this technique. And this is inside root session.

But my question is "without opening ROOT session". can we see the plots and histogram which are saved in a root file. Is it possible in the internet to view contains in remotely where root is not installed? (May be by installing some plugins in the remote PC). Is it possible?

Regards
