Some body please help to code on java using HTTPUrlConnection protocol to download file from URL which need posting of URL parameter.

In clear way,

Suppose there is an URL : www.xyz.com?fileid=123 under which file resides. But this url require post parameter: __EVENTTARGERT=123&__EVENTARGUMENT=&__VIEWSTATE=; then only file come up. Hence , scenario here is we need to post data in that url then only file come up which may be zip or pdf or doc.

From direct URL, i know file can be downloaded easily but from URL that require posting on information, i don't know how to do....so can some help me please.

Thankx in advance

POST requests store their parameters in exactly the same way that GET requests do. The only difference is that GET requests store the parameters in the URL and POST requests store the parameters in the request body.

GET
URL: http://www.example.com/index.jsp?id=123&type=jpeg+image
Body: [empty]

POST
URL: http://www.example.com/index.jsp
Body: id=123&type=jpeg+image
