10g AS Unable to Display PDF

Question

Hi,
I have 10g AS R2 (10.1.2) installed without WebCache. I have a situation where a requested adobe pdf document does not display, instead I just get a blank browser window. This occurs in IE6 and Firefox so it is browser independent. Also, I can reproduce this on many client machines. So it seems that this is independent of the adobe reader install too. There was a time when this worked on this server. In another 10g application server environment with the same codebase this works. There are some config differences between the two application servers environments though, it uses webcache. Ultimately though this worked at one time in the problem environment but stopped working over time. So you know, the requested pdf is created dynamically on the server and sent back to the browser.
In addition to all of that info, the problem AS sends the pdf as content-type of "text/plain", which seems to be the main issue. Where the AS that works sends the pdf as "application/pdf". Below are the two HTTP headers, the first header does not work and the second does not work. Again, the code base is identical although the application server environments are different configurations, where the environment that is broken used to work ok.

Any suggestions on how to get the AS to send the pdf file as an "application/pdf"? Also, I configured WebCache for the broken environment but it produces the same HTTP header shown above and does not work.
Thanks for your assistance.

Answer 1

In addition, here is a header that does not work with webcaching. The header above that does not work does not go through the webcache as I believed. None the less though, the pdf is sent as "text/plain" in this environment.
