    <p>In deploying a version of the Django website I'm working on to Microsoft's Azure service, I added a page which takes a query string like </p> <pre><code>http://&lt;my_site_name&gt;.azurewebsites.net/security/user/?username=&lt;some_username&gt;&amp;password=&lt;some_password&gt; </code></pre> <p>However, I was getting 404 responses to this URL. So I turned on Django's Debug flag and the page I get returned said:</p> <pre><code>Page not found (404) Request Method: GET Request URL: http://&lt;my_site_name&gt;.azurewebsites.net/security/user/?username=&lt;some_username&gt;&amp;password=&lt;some_password&gt;?username=&lt;some_username&gt;&amp;password=&lt;some_password&gt; Using the `URLconf` defined in `&lt;my_project_name&gt;.urls`, Django tried these URL patterns, in this order: ^$ ^security/ ^user/$ ^account/ ^admin/ ^api/ The current URL, `security/user/?username=&lt;some_username&gt;&amp;password=&lt;some_password&gt;`, didn't match any of these. </code></pre> <p>So it seems to be appending the query string onto the end of the url that already has the same query string. I have the site running on my local machine and on an iis server on my internal network which I'm using for staging before pushing to Azure. Neither of these site deployments do this, so this seems to be something specific to Azure.</p> <p>Is there something I need to set in the Azure website management interface to prevent it from modifying URLs with query strings? Is there something I'm doing wrong with regards to using query strings with Azure?</p>

    1. COI found another question that seems very similar to mine: http://stackoverflow.com/questions/12698625/query-string-get-appened-more-than-once But I'm not sure how to implement the suggested solution on Azure. Not the part about rewriting to force https, just the part that prevents the query string doubling.

    2. COLooking into it further, I've tracked the problem down to the path_info variable. I'm using the WSGIHandler provided by Django using get_wsgi_application() in Azure as the WSGI_HANDLER app setting as this tutorial indicates I should be doing: http://www.windowsazure.com/en-us/develop/python/tutorials/web-sites-with-django/ . Looking at the information that handler receives from the environment variables though, it seems as though QUERY_STRING is empty and PATH_INFO has the full url + query string. Which seems to be causing my issues. Not sure if it's a problem with fastcgi or iis though.

    3. COCorrection to the above comment. QUERY_STRING isn't empty. That was my fault in trying to get rid of the double query strings using url rewriting I removed the query string via Web.config file. The root of the issue now is just that PATH_INFO contains the query string and the Django WSGI handler is not expecting it to.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
