Writing Binary files to clients over SSL

[Guest]

In reference to KB article 306654 (which works perfectly otherwise), why does
this method fail if the site is using SSL??? I have a series of content
handlers that write non-ASP.NET files to the browser (dynamic reports, etc.),
but as soon as SSL is enabled on the site, this method no longer works (no
data received by the browser) - I get the 'Page cannot be displayed' error.

Any help appreciated.

TIA,
Mike

Don't underestimate the processing power requirements for SSL. Your
file may sit idle in the web server's output buffer...

Do you use a chunk based approach like KB 306654 suggests, or do you
write the file en bloc?

I tried both...my test file is a 85 KB PDF file.

Ouch! Could be a trivial coding error, like not flushing the response
stream?

LoL...that was my first thought as well!!! But, yes, I did the "5:00 Friday"
check at least 30 times....but to no avail. As soon as SSL is turned off, it
works great....

**sigh**

Hm... can you post your code?
