GET\POST

Hi,
Technically what the merits and demerits of using GET or POST.
GET has limation on data size,whereelse POST doesn't,
GET is URL encoded and POST is form encoded.

Please someother important issues.

If your servlet implements the doGet method, you can call directly:
http://yourserver.com:8080/servlet/Sample
But if the servlet has only the doPost method, you cannot call it this way.

get makes only one connection to the server while as post does a roundtrip and then back

Please can u explain me further,I'm not getting!

Sandy, I am not sure I get what you meant.
Balaji, it's not only a matter of merit/demerit, it also depens on what you want to do. If you have sensive data that you don't want in the URL, you have to use POST. As you posted, GET also has limitations on the size of the data. If you want to handle both, you can just have one call the other.

Hi Bosun,
Well! Even if i send my sensitive data via POST what is the probability that it won't be seen,fo course its not transparent.
I believe a network hacker can easily trap the sensitive data whether it is GET/POST.
I want to know why many web languages are created with GET in mind,for example "Adobe e-forms",
Is there is any performance issues in it. ?

With GET user can bookmark your webpage, and return to it whenever he wants, hoping that he would still get the same info on ur site that he got earlier. Knowing this, u can decide if you want to put sth like session ID embeded in ur URL with GET or not. It entirely depends on ur requirement/design. Besides size, POST makes it a bit more difficult to view the data being posted to the site.

You can consider GET as a little more insecure because all data sent with GET method is save in the server's log files(and/or in the client cache), that could be sniffed later by some non-authorized person.
