Not all methods are supported on HTTP Server.
Not all methods are supported by HTTP Libraries; some only support GET and POST methods.
Do not think Get method is just used for Getter.
It’s a GET method but it’s really used to add bookmark https://api.del.icio.us/v1/posts/add
In some cases, almost all requests are using POST, such as XMLRPC/SOAP.
· Response Code
Some Typical reponse codes:
200 (“OK”)
Everything’s fine.
400 (“Bad Request”)
There’s a problem on the client side.
500 (“Internal Server Error”)
There’s a problem on the server side.
404 (“Not Found”)
Sent when the client requests a URI that doesn’t map to any resource. 404 is used
when the server has no clue what the client is asking for.
SOAP web services use only the status codes 200 (“OK”) and 500 (“Internal Server Error”).
· HTTP Date Time
// Three formats supported for HTTP Date Time.
// Sun, 06 Nov 1994 08:49:37 GMT ; RFC 822, updated by RFC 1123
// Sunday, 06-Nov-94 08:49:37 GMT ; RFC 850, obsoleted by RFC 1036
// Sun Nov 6 08:49:37 1994 ; ANSI C's asctime() format
// Sun, 06 Nov 1994 08:49:37 +0000 ; RFC 2822 (AWS S3 uses this)
