Test 2 - POST Method - Successful

This section provides a tutorial example of testing file upload with the HTTP POST method and multipart/form-data encryption type. The test worked. All input values, including uploaded files, are dumped back on the browser.

The previous test of using the HTTP GET method was not very interesting. In the next test, I changed settings on the UploadInit.html page: Submit method = Post and Encryption type = multipart/form-data.

File Upload Test Settings:

File upload handler: [UploadDump.jspx]
Submit method: [post]
Encryption type: [multipart/form-data              ]

Then I selected the same files on the UploadForm.jsp page, and I got the following dump:

Content-Disposition: form-data; name="email"

Content-Disposition: form-data; name="comment"

 I am uploading two files:
Content-Disposition: form-data; name="file1"; filename="C:\hello.txt"
Content-Type: text/plain

Hello world!
Content-Disposition: form-data; name="file2"; filename="C:\dot.gif"
Content-Type: image/gif

GIF89a   333    !?   ,        D  ;
Content-Disposition: form-data; name="submit"


The output looks very interesting now:
