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?

1.I haven't got any error message on client side
2.when I debug on server I couldn't see the request in
3.readystate doesn't changed
4.I couldn't see the request in
5. the page could called seperately....

the problem likes that IE holds the concurrency request....
 
It is sorta covered in the JavaRanch Style Guide.
