Was only a couple of months ago. I have to agree with Ged. IE3 browsers seemed to ignore the Content-Type header for PDF files. Our system dynamically creates PDF files on request and unless we added a fake parameter of like ie=x.pdf to the end of the URL IE3 would refuse to load the file. Most IE4 builds correctly interpreted the Content-Type ... and then as soon as we began testing IE5 we noticed that the Microsoft ignorance had returned. I have a friend who is a field engineer for Microsoft. I sent a bug report through him to the Microsoft people and he basically ended up saying (not in these exact words) that they told him they had bigger fish to fry than to correct this problem.

Content-Disposition to change type and action?
I've got a form that will (should) send various formats back to the client depending on form values. They may want the results back in csv, pdf or plain html. The form always submits to a .html, and the browser usually expects an html. I've tried setting $r-content_type and even $r-filename to try and get the browser (ie 5 for now) to see it as a non-html file and do the right thing. Then I came across setting Content-Disposition: $r-header_out(Content-Disposition, attachment;filename=\ticket_search.csv\); This has an unexpected result, I get a pop-up asking me what I want to do with the html document (save/exec), if I exec it, it asks me what I want to do with the csv (save/exec). I've never run across Content-Disposition, anyone have a listing of what it does and the options? How do other out there return other mime-types when text/html is requested? Jay

I have a rule in the Apache conf file: RewriteRule ^/reports/ /bin/report.pl [PT] So going to http://www.mysite.com/reports/foo.csv?param1=val1 would be the same as going to http://www.mysite.com/bin/report.pl?param1=val1 except if the page is to be downloaded, the browser will use the name foo.csv. There's another parameter which gets passed to /reports/whatever.csv to indicate that it should generate a csv, and send a suitable Content-Type, but getting the 'name' right solves half the problem.

This also works : http://www.mysite.com/bin/report.pl/foo.csv?param1=val1 report.pl gets called with param1=val1, but if you set the appropriate Content-Type the browser prompt to save it to foo.csv. Works in Netscape and IE. Of course, this is what Content-Disposition is *supposed* to do; ho hum. Cheers, Steve
Re: Content-Disposition to change type and action?
$r-header_out(Content-Disposition, attachment;filename=\ticket_search.csv\); This has an unexpected result, I get a pop-up asking me what I want to do with the html document (save/exec), if I exec it, it asks me what I want to do with the csv (save/exec). I've never run across Content-Disposition, anyone have a listing of what it does and the options? I had this problem too. However, what I got is the opposite. 2 cases. First (file type is plain text): I wanted the browser to pop up a windows for action (save/exec). It got displayed on the browser window (IE5.5) instead of having a popup. Seems if the file type is associated with the browser, it won't pop up the window. However, there must be a way to get this as we want it to, right? Case 2 (file type is Image. gif or jpg): I just want to change the file name for an image that is retrieved through a perl script. For example, if my script is called image.cgi, the file name, when being saved, will be image.cgi instead of the desired filename. However, I ran into Jay's problem if I specify the Content-Disposition header. Anyone knows a way to do this right? Thanks. Bird Lei

My own preference would be to post to some generic script which redirects to another URL with the desired filename extension and proper disposition headers. ------ Ken Williams Last Bastion of Euclidity [EMAIL PROTECTED]The Math Forum
Re: Content-Disposition to change type and action?
Ken's right and yeah, I wanted to stay away from Javascript and keep it simple, it's not the doing of javascript that's bad, it's the redoing. One thing that appears to work is setting the Content-Disposition header value to inline;filename=\search.csv\. (instead of attachment). IE5 seems to do the right thing with that, it pops up one box saying what would like to do with search.csv?. Doing a redir might be a better option then to trust IE4 and NS+ to do it correctly... not to mention trusting IE6 to do anything like IE5.
