    <p>I need to redirect an Ajax call without letting the client know.</p> <p>getPage.php is an application which returns html etc. for a given query.</p> <p><strong>getPage.php?hash=interesting-article-title</strong> and <strong>getPage.php?page=3</strong> returns the same.</p> <p>To avoid the client from having to cache both of these I would like <strong>getPage.php?hash=interesting-article-title</strong> to REDIRECT to <strong>getPage.php?page=3</strong> via PHP header 301 and location.</p> <p>I tried doing this and it returns nothing. The ajax call does not seem to want to be redirected.</p> <p>Does anyone have any idea what could solve this double-cache problem?</p> <p>I would like to use 301 redirects because they are cacheable. This way the browser would automatically call <strong>page=3</strong> when it is told to fetch <strong>hash=insteresting-article-title</strong>.</p> <p>Code examples: </p> <pre><code> function handleInit(event) { if (event.path != "/") { var hash = event.path.replace(/\//,"").replace(/\?/g,""); getPage(hash); currentState.hash = hash; } else { currentState.id = 1; } SWFAddress.addEventListener(SWFAddressEvent.CHANGE, handleChange); } function chapter_forward() { if (!freeze) { freeze = true; getPage(currentState.id - 1); } } function ajax_data(id) { return typeof(id) == "string" ? "hash=" : "page="; } function getPage(id) { $.ajax({ method: "get", url: getPage.php, data: ajax_data(id) + id.toString(), dataType: 'json', timeout: 2000, error: function() { $("#space-3").html('40104 - Request Timeout'); }, complete: function() {}, success: function(result) { handleContent(result); } }); } </code></pre> <p></p> <p>The reason I need the redirect to happen is because I get the id from a HASH when the user uses his back and forth browser buttons.</p> <p>When the user simply navigates back and forth I simply add +1 to the current id.</p> <p>getPage.php returns something like this:</p> <pre><code>{"article_id":"3","hash":"music-in-your-ear","title":"Music in your ear.","html":"Blah blah article 3","modified":"Fri, 20 Mar 2009 02:46:00 GMT"} </code></pre> <p>Thanks!</p>

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.
