topic Disable logout popup with external web redirect in WLC captive p in Wireless

Disable logout popup with external web redirect in WLC captive portal.

Libera Networks — Sun, 04 Jul 2021 06:02:47 GMT

Hello,

We've been using an external web server as source for Captive for one of our customer, and we're hitting a hard issue: some wireless users don't have popup block extensions in their browser, so they got logout popup after proper login. We don't want, if possible, that behaviour, because it may be disruptive for browsing experience for wireless users.

I've read about CLI command "config custom-web logout-popup disable" with 7.2 version, but we're not using custom-web, we're using redirect to external server instead. Is it possible to disable logout popup in that scenario?

Kind regards,

Ignacio Siles.

Have you tried to enter that command? This command was also introduced when using ISE which act as an external webauth, which is similar to what you are doing.

Thanks,

Scott

Hi Scott,

I am faced with similar issue. Will get a try .

Can you help me here with some understanding.

Step1- user types in www.google.com , WLC intervenes and redirects to the url configured under WLAN-security-external url and the override global is checked.

Step2- the login page has the username password field which user fills in and press submit.

Step3- WLC sends a http post with all the required attributes to portal which also include the username / password. In my case the construct looks like this

https://1.1.1.1/login.html?buttonClicked=4&err_flag=0&userna
me=12345&password=7476&redirect_url=https%3A%2F%2Ftestwifi.abc.in%2FCaptivePortal.do%3Fres%3Dsuccess%26userid%3D9717983832&switch_url=
https://1.1.1.1/logout.html

Step4: plc would pull out the username / password , build it in the access request and send to AAA. After receiving the access accept , which is the url that WLC should point the client to. Can you help me understand ,how does WLC treat the redirect_url string and the switch_url string from the above http post.

Step5: In my case , after step 2 , once authentication is done , the user is directed to a successful login page. I am trying to understand, from where did WLC get the url for this successful login page. , is it from step 3.

step6- on the successful logged in page of the portal there is logout button. On pressing that , i am getting the popup window which has the url pointing to

https://1.1.1.1/logout.html?redirect_url=https%3A%2F%2Ftestwifi.abc.in%2FCaptivePortal.do .

Why do i get this popup up. Is there a way i can stop this popup.

The portal is sending http post with the url https://1.1.1.1/logout.html?redirect_url=https%3A%2F%2Ftestwifi.abc.in%2FCaptivePortal.do when the logout button is pressed.

Can you point to some document which can explain the structure of the http post during the entire life cycle.
