Write an RSS reader parsed by the client

I originally wanted to support both IE and Firefox. I found that Firefox has restrictions on the XMLHttpRequest component during my work for half a day. His open method only supports obtaining data from the local website, remote websites cannot be obtained (even if they are not accessed only on their computers ), CodeRemoved. The limitations of IE are a little loose. On your computer, you can use XMLHTTP to access other remote RSS links. However, you cannot place this webpage on a web site, at least not in the default security policy ~~

In this way, the use range of this reader is greatly limited. Is there any way to remove these limitations ~~
