    <p>I'm using <a href="http://iirf.codeplex.com/documentation" rel="nofollow noreferrer">Iirf v2.0</a>.</p> <p>I have the following directory structure:</p> <pre><code>/ /library /library/index.php /webroot /webroot/images /Iirf.ini </code></pre> <p>Where I have a library folder which contains my application, a webroot folder (which contains images, stylesheets etc) and an Iirf.ini config file.</p> <p>I'm wanting to redirect all requests to /library/index.php <strong>if</strong> the file doesn't exist under webroot.</p> <p>eg:</p> <pre><code>Request Response /images/blah.png -&gt; /webroot/images/blah.png /news -&gt; /library/index.php </code></pre> <p>My Iirf.ini config has:</p> <pre><code>RewriteEngine ON RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ /library/index.php [L] </code></pre> <p>Which redirects everything to <code>/library/index.php</code> but I'm having trouble working out how to check if the <code>REQUEST_FILENAME</code> exists under webroot.</p> <p>I've looked at <a href="https://stackoverflow.com/questions/873022/using-altered-request-uri-in-rewritecond-file-exists-check">this question</a> but I don't have access to <code>DOCUMENT_ROOT</code>. It gives me the following (taken from the log):</p> <pre><code>Thu Jul 15 11:46:21 - 760 - ReplaceServerVariables: VariableName='REQUEST_FILENAME' Value='C:\web\favicon.ico' Thu Jul 15 11:46:21 - 760 - ReplaceServerVariables: in='%{DOCUMENT_ROOT}/webroot/%{REQUEST_FILENAME}' out='DOCUMENT_ROOT/webroot/C:\web\favicon.ico' </code></pre> <p>Any help would be greatly appreciated.</p> <p>--- <strong>EDIT</strong> --</p> <p>I've updated my config after more reading and the suggestions of Tim to be:</p> <pre><code>RewriteCond $0 !^/webroot RewriteRule ^.*$ /webroot$0 [I] RewriteCond $0 !-f RewriteRule ^/webroot/(.*)$ /library/index.php [I,L,QSA] </code></pre> <p>And it passes to <code>/library/index.php</code> correctly but it still doesn't check for an existing file (even though it seems to say that it does).</p> <pre><code>Thu Jul 15 14:47:30 - 3444 - EvalCondition: checking '/webroot/images/buttons/submit.gif' against pattern '!-f' Thu Jul 15 14:47:30 - 3444 - EvalCondition: cond-&gt;SpecialConditionType= 'f' Thu Jul 15 14:47:30 - 3444 - EvalCondition: Special: it is not a file </code></pre> <p>I think I'm going to have to contact the author of the Filter.</p>

    1. COHmm, what about `RewriteCond %{APPL_PHYSICAL_PATH}$0 !-f` in that second case (the relative URL isn't a filepath, this wouldn't work in `mod_rewrite` either)? (Or did you determine `%{APPL_PHYSICAL_PATH}` was indeed not what I had hoped it was?)

    2. COUsing `%{APPL_PHYSICAL_PATH}` results in a path like `C:\path\to\folder\webroot/images/buttons/submit.gif` which you would think would be right, but it still fails.

    3. COHmm, (looking at the source code) it relies on the return value from the Windows API function `CreateFile` to check whether the file exists...Which shouldn't have a problem with finding that path, so I don't get it, bah.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
