[Python] cath a timeout of httplib (Python 2.6.5)

Hi!.

I have a problem with httplib and timeout. (I use python 2.6.5 and
httplib)

I have the next code for the http connection (its a WebService Client).

===================================================================
def ejecutaComandos(self,opcion, URL, commandString, conn, id):
#pdb.set_trace()
#fechatransacciones = conciliatorTime()
#status = conn.status
#date_transacc = fechatransacciones.getCompleteDate()
try:
try:
enviaCommand = conn.request("POST", str(URL), commandString)
respuestaCommand = conn.getresponse()
except Exception as e:
print 'Error de conexion: ',e
#intentar=raw_input("Desea intentar nuevamente (S/N) : ")
exit(1)


respuestaWSDL = respuestaCommand.read()
#print respuestaCommand
nom_rand =
str(random.choice('lmnopqrstuvwxyzABCDEFGHIJ'))+str(random.choice('abcdefghijk'))
FileRand = nom_rand+'_tmp.xml'
newFile = creaArchivos(FileRand,self.output)
a = newFile.creaFile('w')
#a = open('../output/responseXML.tmp', 'w')
a.write(respuestaWSDL)
a.close()
#print XP_LOG+'respuesta de HLAPI
recibida...'+str(date_transacc)
#return respuestaWSDL
return a.name
#except httplib.HTTPException as he:
except Exception as he:
print "Error de ejecucion ...: %s " % (he)
else:
print "Error inesperado..."
===================================================================


I need resend the command when a timeout error present, my idea its use a
"while".



===================================================================
while (intentar=='S'):
try:
enviaCommand = conn.request("POST", str(URL), commandString)
respuestaCommand = conn.getresponse()
raise Exception
except Exception as e:
print 'Error de conexion: ',e
intentar=raw_input("Desea intentar nuevamente (S/N) : ")
if (intentar=='N'):
exit(1)
===================================================================

But the information of "enviaCommand" it is lost, and it been only "None",
then fail resend.

As I can resend the information without the command loses itself.

Greetings and tanks!.
