Hi,guys, I have some trouble that: I create a page that support upload progress,the implent method is invoke the from that contains the file field 's submit method, then use the xmlhttprequest to retrive the upload progress from server when the form submit is going on... the problem is , when the domain name of submit url(like http://upload.a.com/a.aspx) same as the domain name of progress data url(like http://upload.a.com/p.aspx) the xmlhttprequest that point to the progress data url doesn't return...else I change the progress data url to http://p.upload.a.com/p.aspx, the solution works....
why, how to solve the problem???what cause the problem???
What is the problem is more of a question you need to answer. Are you getting error messages? When you trace the code are you seeing the server side page being called? Is the readystate changing? Are you seeing requests when you debug? Can the page be called seperately (loaded traditionally) without an error?
