All,

I am using Net::HTTP to make requests for URLs in my app. When I get a  
bad server, I get “Bad file descriptor - connect(2)” message on a  
ERRNO:EBADF error.

Can I catch with rescue or otherwise gracefully react to that error?

Thanks,  
Wes

Of course.

rescue Errno::EBADF =\> e

# handle me, baby!

end

I just caught it by mistake when I saw this.

I was making a Java distinction between Errno and Exception - there is  
probably some diff. that I don’t understand yet, but this will work for  
now!!!

Thanks,
