Wt

Version: Wt 3.2.0

I'm Attempting to download a pdf file, that is being generated on the fly. The .pdf is created fine. I can manually goto the server find the .pdf that was created and open it. Everything seems good.

The problem is when the website attemps to send the .pdf to the user.

//write the pdf to disk
std::ofstream f(newFileName.c_str(), std::ios::out | std::ios::binary);
pdfImage.write(f);

//create resource to hold the pdf
WFileResource *fileResource = new Wt::WFileResource("application/pdf", newFileName);
fileResource->setDispositionType(Wt::WResource::Attachment);
fileResource->suggestFileName(newFileName);

WApplication::redirect(fileResource->url());

Client: Ubuntu Chrome 16.0.912.63; I get the Keep/Discard prompt. Click Keep. Transfer always halts on 5.8k out of XXXXX.

Open up Chrome's Developer Tools:

I can see the event:

And gives me the error "Resource interpreted as Other but transferred with MIME type undefined."

Now If I increase the buffer size of the WFileResource to say 32k, I can receive the file and open if fine. Of course the above error message is still present, or If I attempt to send a file bigger than 32K, obviously I get the error.

At one point all of this worked. Maybe 3.1.11, but I can't be sure the switch to 3.2.0 caused it.

I'm guessing it may be some setting somwhere given the pdf is being generated properly.

Not to sure where to look to figure this out.
