AltostratusExample passing information to a application from APM
I guess this is more of a request for a how would I question then anything and hopefully example articles or blogs exist already. What I would like to understand is after authenticating someone...
Hi Ravager,
Your question inspired me to do some testing with passing APM session variables into sessionStorage. First I created an iRule to add the APM session variable into the sessionStorage of the webbrowser. And a simple webpage to query the browsers sessionStorage.
iRule:
when ACCESS_POLICY_COMPLETED { set username [ACCESS::session data get session.logon.last.username] set html "<!DOCTYPE html>" append html "<body onload=\"location.reload()\"></body><script lang=\"javascript\">" append html "if (typeof(Storage) !== \"undefined\") \{" append html "sessionStorage.setItem(\"username\", \"$username\");" append html "\}</script></html>" ACCESS::respond 200 content $html }HTML to put on the webserver:
<!DOCTYPE html> <html> <body> <div id="result"></div> <script> if (typeof(Storage) !== "undefined") { document.getElementById("result").innerHTML = "Username: " + sessionStorage.getItem("username"); } else { document.getElementById("result").innerHTML = "Sorry, your browser does not support Web Storage..."; } </script> </body> </html>Here you can see the username is put into the browsers sessionStorage.
Like always with the F5 BIG-IP, there is more than one way to do it. For example, you could also use HTTP Headers to pass information from APM to the web application. See:
