Http 502 and 503 errors

George George

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

Thanks Ryan!

If client request is not correct (e.g. missing some fields in Http header and body), then what is the common error code? Not 502/503?

regards,

George

Can you read? These are pure server side errors. If you are not controlling the server side, then you can't do anything about it.

Sorry Ryan,

I have not made question clear enough. I am not developing server side application, but writing an Http client to request some pages for data to use.

My question is, if at Http client side, there is 502 or 503 error, how could the client improve itself to reduce some error?

- Is it a client side issue? I am not sure whether it is caused by missing/wrong fields of some Http session/cookie/headers I sent to server?

- Is it a pure server side issue?

regards,
George

I am sorry, but I have to ask this. Have you ever heard of Google? I did a search for "HTTP 502 Error" and the first result gave me this...

http://www.checkupdown.com/status/E502.html

then I did a search for "HTTP 503 Error", and the second result gave me this(from the same site as above)...

http://www.checkupdown.com/status/E503.html

that took me a total of 10 seconds. How long did it take you to create this topic?
