问题
I have this line of code in my JSP. (I'm using struts 1.3)
<html:form action="screening/mine.do" method="post"> . . . </html:form>
When the action corresponding to mine.do is invoked (using struts-config.xml), the page is getting submitted as GET instead of POST. All the request parameters including the required ones are getting lost due to this. This issue occcurs only in IE-9.
The response remains as POST when I use other versions of IE or any other browsers. How do I make the response to remain as POST in IE-9 ?
EDIT : I observed one more issue in this. Whenever the page is rendered in a new window, this issue occurs. Other places, the POST works fine in IE-9.
Also, this issue occurs in Win7/IE-8, but works absolutely fine in XP/IE-8. Is there something to do with the OS as well???
Any solutions would be useful.
Thanks!!

This issue was happening due to a security setting in IE in Windows 7. It also happens in IE-8 of Win-7. (But works fine in IE-8 of Win-XP)
There is an option of Enabling/Disabling protected mode in IE of Windows-7. This is a new feature present in IE of Vista/Windows-7 and this option is enabled by default for “Internet” zone and “Local Intranet” zone(or any one of them). Disabling at these 2 places solved the issue.
Tools -> Internet Options -> Security -> Internet/Local Intranet -> Uncheck on the "Enable protected mode" option.

TL;DR: Ensure the two sites are in the same zone as well. I had sites in two different zones and calling up the zone stack broke IE.
For anyone that stumbles across this (like I did), but finds that the Protected Mode setting doesn't resolve it, I wrote this up on another thread: https://stackoverflow.com/a/12167814/649249
Resolved it for me.

Try this: method="POST".
The standard specifically states that method can have the value GET | POST (note the caps).

We have noticed that there are some security warnings that halt the processing in order for the user to acknowledge. Once the use acknowledges the warning the browser sends a get rather than a post. This has been happening in IE8, not sure if it still happens in IE9.
