I have a code like this

def connect(redirect=3)

```
# Do we have a url to process do we?? if not simply return
if not @uri
    return nil
end

begin
   @clnt = HTTPAccess2::Client.new()
   @clnt.set_cookie_store("cookie.dat")
   @resp = @clnt.get(@uri)
   @code = @resp.status.to_s
   @message = @resp.reason
 rescue SocketError
    @code = "404"
    @message = "Not Found"
rescue Exception => e
     puts "#{self.class} Exception connecting to #{@uri.to_s} : 

```

#{e.to\_s}"  
@code = “408”  
@message = e.to\_s  
end

@resp  
end

this works as expected but some times (not always) I get an error and  
the  
scripts bails out.

c:/ruby/lib/ruby/site\_ruby/1.8/http-access2.rb:1466:in `gets': Invalid argument (Errno::EINVAL) from c:/ruby/lib/ruby/site_ruby/1.8/http-access2.rb:1466:in`parse\_header’

from main.rb:208

I think I am rescuing all possible things that could go wrong here so my  
script should continue ignoring this error but the scripts stops.

How can I rescue this??

a simple

rescue =\> e

should work as Errno is derived from SystemCallError (which inherits  
from StandardError).

See Pickaxe II page 108 for details.

Actually I don’t know why catching Exception doesn’t work.
