After doing some additional searching, I found out it is not a Struts issue, but a Tomcat issue. Specifically, how Tomcat appends cache control headers when running under a secure context (SSL).
Although this isn't a problem for Safari or Firefox, it is a problem with Internet Explorer because it prevents the user from downloading (saving/caching) files via SSL. See the link below for more information: http://marc.info/?l=tomcat-user&m=111811136603781&w=2 The solution that worked for me was to add the following response headers in my action class that extends org.apache.struts.actions.DownloadAction: response.setHeader("Cache-Control", "cache"); response.setHeader("Pragma", "cache"); response.setHeader("Content-Disposition", "attachment;filename=" +fileName); My struts-config action looks like this: <action path="/filetransfer" type="com.myproject.actions.SSLFileDownloadAction"/> My struts link looks like this: <html:link action="filetransfer?file=myPDF.pdf">My PDF</html:link> Some great examples of how to implement the struts download action can be found here: http://wiki.apache.org/struts/StrutsFileDownload Thanks for the suggestions/help. -----Original Message----- From: Wendy Smoak [mailto:[EMAIL PROTECTED] Sent: Saturday, October 18, 2008 7:56 PM To: Struts Users Mailing List Subject: Re: Download PDF File in Internet Explorer w/SSL On Sat, Oct 18, 2008 at 5:06 PM, gcj <[EMAIL PROTECTED]> wrote: > Despite the numerous posts/suggestions I have read/implemented on the > subject, I am not able to download or display existing PDF files from my SSL > struts/tomcat application using Internet Explorer. What did you do, and what happened? Without a description of the error it's hard to help. Your post initially reminded me of a problem I had long ago serving PDFs... Internet Explorer has a problem displaying non-HTML content over SSL as the result of a form POST. In short, you have to send IE some HTML before you send it the bytes of the PDF, or it will complain. If that sounds like it, I have a very old wiki page on the topic... http://wiki.wsmoak.net/cgi-bin/wiki.pl?NonsecureContent (But then later you say a plain link didn't work either, so maybe not.) -- Wendy --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
