当网页不在本地主机上运行时，IE中的window.sessionStorage问题

Question

I've created a login webpage that sends a userId and password to a Java servlet via javascript. When the servlet validates the credentials, it sends a response to the webpage, and I store the userName in sessionStorage by using:

sessionStorage.userId=uName; //read uName from servlet & save userId for this session

After this, I navigate to a new page by using window.location.replace("home.html") , and in home, I read userId for further use.

I'm using Apache Tomcat v8.0 on Windows .

I'm running my login page on the browser via:

1. localhost:8080/login.html
2. 10.11.12.13:8080/login.html (from my machine's IP, given in ipconfig )

The setup works fine in Chrome and Firefox for both localhost and IP.

However, in IE11, sessionStorage works correctly only when I use localhost:8080. When I supply the IP address, sessionStorage.userId doesn't retain its value.

Since IE is working fine for localhost, I know that Window.sessionStorage is supported by IE.

I've also tried saving the userId in a separate .js file, but that value is lost as soon as the page navigates.

Any suggestion would be earnestly welcomed. Thanks

Answer 1

I found my answer on: Local website renders differently using (IP address or machine name) vs localhost?

Turns out, that the issue was with my html, not my javascript. I added this line in my head tag:

<meta http-equiv="X-UA-Compatible" content="IE=11">

and that fixed it.

Don't know if this helps but there was a time where console only was available if you had devtools open which lead to some exceptions and not working code.

Do you use the latest version of ie11?
