hi,
i've a question: lets say i write some software (e.g. with perl) that works web based (all you need to use that software is a proper webbrowser). now lets say i publish it under GPL. If now someone downloads the code and changes it and then puts it on his webserver so that everyone can use it there, does he have to publish the changes under GPL? I mean, its clear that if someone changes it and then pass the changed program on, he has to publish that version under GPL. but if he doesn't pass it on, if he just makes it useable, but it runs on his own webserver, is that the same? All he does is modifying the code and running that version on his public webserver.
Would be nice if someone could explain me why he has to publish it under GPL or why not.
regards, moritz
