Content-disposition attachment filename has different results in Firefox and IE

In Firefox, you need to enclose the filename in double quotes to get the name you want, or if you have a space, you will lose the part behind the space.
And IE will turn the space to _, so also need to Httputility.urlpathencode method to deal with the next name.
If Firefox also uses Httputility.urlpathencode to process names, spaces will be replaced with "%20".
