Coding 101 27: Perl: Reading POST Form Actions

Ivory Tower

Let's play with some POST! Last week we used the "GET" method within the HTML "FORM" tag to get information from the browser.


Would you care to name this creature?




  • If we type "My Dog" into the field and click Submit, it will create a URL that calls the script "animal_name.pl" and passes it the value "My+Dog"
  • The resulting URL would read: cgi-bin/bunny.pl?NameOfCreature=My+Dog Now we're going to use "POST"
  • While "GET" was fine for little pieces of data entry from the user, "POST" is the preferred methods for sending longer strings and combinations of HTML FORM data.
    • Unlike GET, POST requests have no restriction on data length. POST is NOT secure, but it DOES have a few security advantages to GET
    • GET requests remain in the browser history, CAN be cached and can be bookmarked.
    • POST requests are NOT retained the browser history, nor are they cacheable or bookmarkable.
