Hi Nirmal,

print(httpClient.responseText); writes the response back.

@Sajith I need to handle this from Jaggery side.

 Hi,
 Thanks Inshaf. But this won't solve my problem. I have already done the

 This chunking is the problem.

 Hi all,

 I'm trying to download a file from a given URL (File get downloaded if
 we directly go to the link via browser), in a jaggery app.

 I need to get the file to the Jaggery backend and send it to the
 browser so that file should get downloaded. I tried this by sending a get
 request to the relevant URL, setting all the headers received from get
 response to the jaggery response and printing the payload as shown below.

 var httpClient = new XMLHttpRequest();
 httpClient.open('GET', url, true);
 httpClient.setRequestHeader('COOKIE',
 session.get('MGT_SESSION'));

  //copy header details
 var contentType =
 httpClient.getResponseHeader(Content-Type);
 var transferEncoding =
 httpClient.getResponseHeader(Transfer-Encoding);
 var vary = httpClient.getResponseHeader(Vary);
 var date = httpClient.getResponseHeader(Date);
 var server = httpClient.getResponseHeader(Server);
 var contentDisposition =
 httpClient.getResponseHeader(Content-Disposition);

 response.addHeader('Content-Type', contentType);
 response.addHeader('Transfer-Encoding', transferEncoding);
 response.addHeader('Vary', vary);
 response.addHeader('Date', date);
 response.addHeader('Server', server);
 response.addHeader('Content-Disposition', contentDisposition);

 print(httpClient.responseText);

 A file get downloaded as expected. But is is a corrupted file with
 less size than actual size of the file.

 I think the reason for this is the data is coming as chunked data
 packets. The 'Transfer-Encoding' header value is 'chunked'.

 Any hint on resolving this is much appreciated.

 Thank You,
 Vinod

[Dev] [Jaggery] Download files from URL

var vary = httpClient.getResponseHeader(Vary);
var date = httpClient.getResponseHeader(Date);
var server = httpClient.getResponseHeader(Server);
var contentDisposition =

response.addHeader('Content-Type', contentType);
response.addHeader('Transfer-Encoding', transferEncoding);
response.addHeader('Vary', vary);

Hi Vinod,

Since you are using Jaggery, you can use JavaScript to create and download
a file. You can have a look on [1], but not sure whether it aligns with

Re: [Dev] [Jaggery] Download files from URL

Where are you reading the chunked incoming data? I can't find it in the
code you pasted.

So, the data is chunked and you have to read the data correctly. Spec:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.6.1
