I have a JSP page, which allows users to submit specific info to a web-app. Apart from the form parameters, the POST request needs to contain an XML string in the body of the request too.
Now, I am not sure how to set this XML in the body of the POST request. A normal form submission results in POST with content-type as 'application/x-www-form-urlencoded'. But, in this case, the body will contain XML too which should reflect in the content-type header. Is this kind of paradigm supported in HTTP? How can I do this?
No, that wouldn't be reflected in the content type. The only option is to submit the XML as straight text - either in a text (or hidden) field, or a text area. There are no provisions for somehow "embedding" XML in an HTML form.
