Re: Tomcat server not considering Mime Type - Request urgent help!!
As Niranjan said, pls validate the headers first and it may be not the case in Tomcat7 but there are multiple points which must have updated probably triggering it. Only way to verify is set Content-Disposition header accurately and verify if browser can see it On Fri, Jan 15, 2021, 8:41 AM Jonnalagadda, Swathi (External) < swathi.jonnalaga...@xerox.com> wrote: > Hi Chris > > My web application is trying to open the xls file by passing the file to > request.getDispatcher method.

RE: Tomcat server not considering Mime Type - Request urgent help!!
Hi Chris My web application is trying to open the xls file by passing the file to request.getDispatcher method. It is supposed open up download dialogue box but it is not doing. If I set the content-type explicitly to response it is showing up the box. With Tomcat 7 it was never an issue and it used to consider mimetype that is defined in web.xml but in Tomcat 9 not sure why it is not considering mime-type.

Hi again. Sorry for the noise. The page which you quoted (https://www.geeksforgeeks.org/http-headers-content-disposition/), itself contains a formal reference to RFC 5987 (https://tools.ietf.org/html/rfc5987), which formally defines the extended "filename*" header parameter below.

Re: Tomcat server not considering Mime Type - Request urgent help!!
What everyone is telling you is browser is not seeing right headers.. You can modify your tomcat settings as well as apache2 settings to log outgoing content type header. If tomcat and apache2 headers match, problem is in your tomcat side. If there is a mismatch and tomcat is sending right headers. then problem is on apache2 side. You can directly connect to tomact using curl or even in the browser to bypass apache2 and see if it works. How is response returned? How do you set the extension of the file? You said file generated dynamically, are you sure your servlet or whatever service handler you have there is not sending incorrect header? I am not sure, but I believe global mime type settings are only for static files that tomcat serves. Any dynamically generated content has to be managed by response handler. More knowledgeable people here can correct me if I am wrong.

RE: Tomcat server not considering Mime Type - Request urgent help!!
This issue is not resolved yet. The extension of file is clearly .xls but I see content-type in response header is set to text/html. Please note that the request initially hits apache2.4 server which is redirected to tomcat9 server after successful authentication at siteminder. The connection is configured via ajp connector. Is there a possibility that the apache server is overwriting the content-type header in response ? Please advise.

Re: Tomcat server not considering Mime Type - Request urgent help!!
I have found getting browsers to handle objects correctly is problematic and needs to be specific to the use case in the html link.

Thank you for the email We could see that when we try to open the xls file separately the browser shows dialogue box to save it so it is nothing to do with browser settings Could you please advise if I am missing out any setting here.

Pls check http response headers for the request to confirm if it's returning proper headers. Once they are in place then it may be to do with browser settings not processing headers.
