Subject [users@httpd] MOD_PROXY Open CSV Content Into Excel
Date Wed, 20 Oct 2010 15:50:48 GMT
Hello All
We develop web applications using Weblogic and JSP pages.   Our web app has the functionality
to export to excel where data is pulled from a database and presented to the web client, at
that point the web client recognizes the content stream and opens excel with the CSV file.
  The code from the JSP page is below:

      response.setHeader("Expires", "Sat, 6 May 1995 12:00:00 GMT");
    response.setHeader("Cache-control", "no-store, no-cache, must-revalidate");
    response.addHeader("Cache-Control", "post-check=0, pre-check=0");
    response.setHeader("Content-Type", "text/html; charset=" + encoding);
    response.setHeader("Pragma", "no-cache");
            response.setHeader("Content-Disposition", dispType + "; filename=grid.csv");

                dispType = "attachment"
                encoding = "UTF-8"

When accessing the Web app directly, this works great, but when accessing  through an Apache
Reverse Proxy, the CSV content is displayed in the browser window.

Our Reverse Proxy settings are listed below.
<!--http.conf snip-->
ProxyRequests Off
ProxyPreserveHost Off

ProxyPass /app/ http://internalhost/app/
ProxyPassReverse /app/ http://internalhost/app/
<Proxy "https://*/app/*">
        Order deny,allow
        Deny from All
        #Allow from Us
        Allow from
        #Allow from Customer
        Allow from 162.x.x.x/24
<!--http.conf snip-->

Has anyone seen this before?
