Re: [ecf-dev] Changing keepAlive property of ECF Generic

Hi Scott.

Thank you for the property, now its working nice! :)

As you have suggested, I've added a +1 in the ECF Documentation
Priorities wiki [1] to a new entry: "ECF Configuration (Properties
list)". Also, I've created a new wiki page to enumerate the properties
under the EIG [2] (and also some examples for configuration properties
for some available providers). Please, modify (or delete) it if you
don't find it adequate.

BTW, I would like to download your presentation here [3], but it seems
the pdf is gone.

Finally, the Broken Pipe Exception I receive is in [4], and yes, I
would like to avoid it in the log (but this is not so important,

Thanks again for your help!
