Mechanize users - Dec 2006 - Retrying requests

I use this method to retry my requests if there are retrieval problems.

def with_retries(num_retries = 4)
   begin
     yield
   rescue Errno::ECONNRESET, Errno::ECONNABORTED, Errno::EHOSTUNREACH,
Errno::ECONNREFUSED, Errno::ETIMEDOUT, Timeout::Error,
WWW::Mechanize::ResponseCodeError
     num_retries -= 1
     retry unless num_retries < 0
     raise
   end
end

So I can try three times to get a page:

with_retries(2){page.click()}

before the outer method raises an exception.  But I''m not really sure
if I''m
catching all the right exceptions.  Anyone know?

                                                              -- Zach.
