Using JavaScript protocol from .NET

**fil** · July 5th, 2011, 11:22 PM

Is there any way for a .NET client to connect using the Web Client (JavaScript) protocol?

hi,
the javascript protocol is not documented nor public, the only way to use it is leveraging our html client library

I've been wondering if you can host the HTML client library inside a .NET app... doesn't sound like anyone has done this

no I don't think anyone did that,
not sure how you would do it, the html client library relies on some browser's properties and methods.

why do you need to do that? If you can expand on your requirements we may be able to suggest an alternative way.

Thanks for the reply. Essentially I have a .NET front end that I want to stream data into, but the server only currently has web clients. I don't think the server supports non-web clients, since that is a different protocol is that right?

Hi Fil,

Yes, I confirm you need to use a paid edition of Lightstreamer Server (at least Allegro + .NET Client API) in order to stream data to .NET Clients.

Kind regards,
Alessandro

Good point Alessandro, but that was not the intention of my question.

The issue is having a .NET client that can traverse the internet just like web clients (ie. using HTTP etc.). This is the advantage of the protocol as I see it..

Hi Fil,

The .NET Client API of Lightstreamer does use HTTP to traverse the Internet, exactly as the HTML Client API. The difference is that these two APIs use slightly different application protocols on the top of HTTP. But for everything concerning firewall and proxy traversal, they are exactly the same. So you can definitely leverage the provided .NET Client API.

Hope that helps.
