Download pdf over SSL

[Steven Rigney]

I have a site that has to run over SSL. One of the pages has a link
to download a pdf file. When I click this link I get an error that
Internet Explorer cannot download the file.

I found this problem document in a Knowledge Base article at
Microsoft. http://support.microsoft.com/kb/316431

I have been playing for a day trying to get the Pragma No-Cache header
removed from the header. I can't find anywhere that it is actually
being set, even when digging through the Play framework, but when I
run Fiddler I can see the headers that are being returned and this is
included.

How can I get the Play Framework to remove the Pragma No-Cache
header?

[Steven Rigney]

I want to make sure I state this correctly. I found in Fiddler that I
was looking at the previous page and not at the actual download of the
pdf file.

The header when downloading the pdf does not have have the Pragma No-
Cache, it does have Cache-Control: no-cache="set-cookie"

I need to be able to not have the Cache-Control header included in
order to download the pdf file.

I'm not sure exactly which fix worked yet, but I am working again. I
hacked the Play framework to remove the no-cache header. However
after I did that I was still having it show up. I found that WAS adds
no-cache when adding cookies. I had to change a Websphere
configuration value to prevent the cookies from adding the no-cache
value. That allowed it to work.

Hi,

I'm having exact the same issue. I have this setup:
Play 1.2.4 as war in tomcat7 and apache2 ajp-proxy in front of it.

Can anybody help me with this issue?

All help appreciated!

Thanks in advance,
Cyrille

Hi

In the pdf module, there is some liines to handle this :

            // FIX IE bug when using SSL
            if(request.secure && isIE(request))
                response.setHeader("Cache-Control", "");



    private boolean isIE(Request request) {
        if(!request.headers.containsKey("user-agent"))
            return false;
       
        Header userAgent = request.headers.get("user-agent");
        return userAgent.value().contains("MSIE");
    }

You may try to do the same for your pdf.

Hi,

Implemented your solution and it works.
Made one adjustment. According to this site

response.setHeader("Cache-Control", "no-store, no-cache");

should work also. Removing "no-store" or reversing the order, downloading will fail again.
Tested it and: BINGO!

Thanks for your help.

Cyrille
