RE: Stream pdf to browser

Hi Rick,

From your description, you're using webservice to expose some PDF stream
from backend file or database and stream them to web application(let web
application flush the pdf content to client). currently you're wondering
how to make the web application display the pdf stream download in a
separate browser window from the main window(which trigger the postback)
,correct?

Based on my experience, a typical approach to do this is a below:

1. You should create a separate page which dedicate to retrieving binary
content from the webservice(that return pdf buffer) and stream it out to
web page response). This page will use some url querystring as parameter to
identify which pdf file to retrieve from webservice.

2. In your main web page, when you click a button and postback to retrieve
pdf stream, you just simply register some client-side script that will open
a new browser window, the url is just the dedicated page created in #1 and
append some url querystring (indicate which pdf file to open).

How do you think?

Sincerely,

Steven Cheng
