Python CGI Programming : GET and POST Methods:
S.No
Differences in
HTTP Requests
GET
POST
1
Syntax
Uses the Keyword ‘get’.
Uses the Keyword ‘Post’.
2
How are inputs sent?
Along with URL appending after the symbol ‘?’.

8
Browser History

9
Bookmarking
It allows the URL to be bookmarked and, in turn, the sent data.
There is nothing to do with the sent data even the web pages are bookmarked. As the bookmarked pages do not store any user information.
10
Caching
The cached pages store the user input and allow future retrieval.
The cached pages never store the user input.
11
Refresh or Back
The Refresh or Back actions do not re-execute the request if the older executions remain in .the cache memory. Also, such a retrieval from the cache happens without any alert message to the user. Therefore, the user may think that it is the latest but, in turn, the server may contain a different data.
The Refresh or Back actions fetches the data from cache only after sending an alert message to the user. The user may cancel it and can even re-execute it to fetch the latest data from the cache.
12
Hacking
It can be done easily.
It is difficult to hack.

It is best suited to send many sensitive data such as passwords, bank account details, etc where security is of most concern.
