web container not downloading pdf file

Hi,
I am founding a way to download pdf file when clicking on link in web container getting the following warning :
"W/chromium: [WARNING:spdy_session.cc(3047)] Received RST for invalid stream"
I am pretty sure that some one come up with some solution and help me with this issue.

Start by reproducing the PDF-link download in the Android web container and inspect the existing web-container download handling. The issue provides no file or test entry point; done means the PDF downloads when the link is clicked without the reported Chromium warning.
