Re: How are js-interpreters run in presence of concurrent connections to javascript-show dynamic page?

Hi Dmitry, I didn't write the code but my understanding is that we  
look for an unused OS process for the requested language; if we find  
one, we use that process, if not, we spawn a new one.  There is also a  
comment in the code

So the simple answer to your question is that the responses to  
concurrent _show requests will be generated in separate OS processes.   
Sorry for the radio silence on user@, it's not usually the case.  Most  
of the devs are listening there too.  Best,

Adam

Thank you for reply ;)

I will dig in code a bit later for now it was question for having some
guess of process.

Idea of having js on server side, together with erlang inspires a lot ;)
