如何设置请求标头

假如http有这样的标头属性：Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*
可以这样设置conn.setRequestProperty("Accept","image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*")那这个：POST /dongyusong/web/upload/uploadFile.asp HTTP/1.1
应该如何设置呢，是在java代码里
求高手帮忙
