What is the difference between doGet() and doPost() methods ?
The difference has given below......
doGet | doPost |
In doGet Method the parameters are appended to the URL and sent along with header information | In doPost parameters are sent in separate line in the body |
Maximum size of data that can be sent using doget is 240 bytes | There is no maximum size for data |
Parameters are not encrypted | Parameters are encrypted |
DoGet method generally is used to query or to get some information from the server | DoPost is slower compared to doGet since doPost does not write the content length |
DoGet should be idempotent. i.e. doget should be able to be repeated safely many times | This method does not need to be idempotent. Operations requested through POST can have side effects for which the user can be held accountable for example updating stored data or buying items online. |
DoGet should be safe without any side effects for which user is held responsible. | This method does not need to be either safe. |
