Http 502 and 503 errors

[George2]

Hello everyone,


I am writing a simple client which downloads Pages from Http Web site. Sometimes I received errors like 502 or 503 (Http error code), and I am wondering,

- What do they mean?

- Are they pure server side issue? Or I could improve by adding some additional information to my Http request (e.g. provide user name and password, provide locale information?)


thanks in advance,
George

You obviously have not tried "google http error codes", as the first 5 links there will give you the answer in almost identical ways.
