403987 - Content-Type: multipart boundary is removed when XMLHttprequest is sent

Status: RESOLVED DUPLICATE of bug 393968

(Core :: DOM: Core & HTML, defect)

Description

[Kris]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.9) Gecko/20071025 Firefox/2.0.0.9
Build Identifier: 0.8

When a XmlHttprequest is created and the content-type is set to 

multipart/form-data; boundary=45309FFF-BD65-4d50-99C9-36986896A96F

it is replaced with the following:

multipart/form-data;charset=UTF-8

This causes the web server to return the error: Error in file upload: the request was rejected because no multipart boundary was found




Reproducible: Always

Steps to Reproduce:
1.Start Prism with a web page that contains a javascript to create the XmlHttpRequest
2.setRequestHeader('Content-Type',"multipart/form-data; boundary=45309FFF-BD65-4d50-99C9-36986896A96F"); }
3.Create a content containing the form-data strings
4.send the XmlHttpRequest
Actual Results:  
The Header of the request send is changed into:

Content-Type: multipart/form-data;charset=UTF-8

Expected Results:  
What happens in FF2.0.0.9 browser with the same web page/javascript the header contains:

Content-Type: multipart/form-data; boundary=45309FFF-BD65-4d50-99C9-36986896A96F

Prism doesn't do anything differently than Minefield/Firefox, it's just got a newer Gecko.
