How to retrieve a client's IP adress?


I want to know if there is a way to retrieve a visitors IP adress using JavaScript.
I could also use JSP if that works better.

Please advise.

In JSP it's quite easy:

out.print( request.getRemoteAddr() );
out.print( request.getRemoteHost() );

That works on a "standalone" page, but this page in particular is
included into another jsp, and the only IP I'm getting is that of the current server.

Sorry for not mentioning this earlier.

That's a bit more tricky, since the request is indeed coming from within your server when you do the include.  It's a sort of chain going on.

There might be a way for the 'parent' jsp to find it and then pass the IP as a parameter to the child in some way?

Thanks, I'll try that.

Do you know how 'intense' this request is on the server, as the parent is used to present almost everything else on the site.

Pls e-mail me if you do.

Sorry I've not got much experience of JSPs.  We tend to develop in Perl/Javascript mainly.  I only know a few little snippets about JSPs.
