Questo ha fatto sì che molti siti sono stati sviluppati per funzionare con il browser più diffuso, piuttosto che per essere compatibili con gli standard di gruppi come il <a href="/wiki/W3C" class="mw-redirect" title="W3C">W3C</a> e l'<a href="/wiki/Internet_Engineering_Task_Force" title="Internet Engineering Task Force">IETF</a>. Alcuni siti, quindi, utilizzano una tecnica detta "user agent <a href="/wiki/Sniffing" title="Sniffing">sniffing</a>", la quale consiste nel restituire un contenuto specifico per lo user agent che fa la richiesta (o nel restituire il contenuto solo se un determinato user agent lo richiede). Molti browser, quindi, sono in grado di falsificare, con una tecnica detta "user agent spoofing", il loro user agent in modo da avere del contenuto. Molti di questi browser aggiungono comunque la loro vera identità alla fine della stringa. </p><p>Un recente esempio può essere Internet Explorer, che utilizza una stringa che inizia con "<kbd>Mozilla/<version> (compatible; MSIE <version>...</kbd>", in modo da ricevere contenuti scritti per <a href="/wiki/Netscape_Navigator" title="Netscape Navigator">Netscape Navigator</a>, il suo principale rivale ai tempi della sua creazione e del suo sviluppo. Va sottolineato che non ci si riferiva al browser <a href="/wiki/Open_Source" class="mw-redirect" title="Open Source">Open Source</a> <a href="/wiki/Mozilla" title="Mozilla">Mozilla</a>, che fu creato successivamente, ma al <a href="/wiki/Nome_in_codice" title="Nome in codice">nome in codice</a> di Netscape (nonché il nome della sua <a href="/wiki/Mozilla_(mascotte)" title="Mozilla (mascotte)">mascotte</a>). Questo formato di stringa fu poi copiato da altri browser, in parte a causa del fatto che Internet Explorer, a sua volta, divenne il browser dominante. </p><p>Quando Internet Explorer diventò il browser più diffuso, rivali come <a href="/wiki/Mozilla_Firefox" title="Mozilla Firefox">Mozilla Firefox</a>, <a href="/wiki/Safari_(browser)" title="Safari (browser)">Safari</a> e <a href="/wiki/Opera_(browser)" title="Opera (browser)">Opera</a> implementarono sistemi grazie ai quali l'utente poteva selezionare (o, in alcuni casi, inserire) una stringa falsa da inviare, ad esempio quella dell'ultima versione di Internet Explorer. Alcuni (come Firefox e Safari) copiano esattamente la stringa del browser, mentre altri (come Opera) aggiungono alla fine della stringa il vero nome del browser. Quest'ultimo sistema, ovviamente, produce una stringa con tre nomi e versioni di client diversi: per primo, la stringa dice di essere "Mozilla", poi dichiara di essere "MSIE" (Microsoft Internet Explorer) e infine aggiunge il vero nome, ad esempio "Opera". </p><p>Oltre ai browser, anche altri programmi che usano il protocollo HTTP, come la maggior parte dei <a href="/wiki/Download_manager" class="mw-redirect" title="Download manager">download manager</a> e dei <a href="/w/index.php?title=Browser_offline&action=edit&redlink=1" class="new" title="Browser offline (la pagina non esiste)">browser offline</a>, hanno la capacità di cambiare come l'utente vuole la stringa inviata al server. Questo, probabilmente, viene fatto per mantenere la compatibilità con quei siti che bloccano determinati programmi di questo tipo, a causa del fatto che spesso sono utilizzati con scarso criterio, fino a sovraccaricare il server. </p><p>Questo circolo vizioso pare voler continuare nel campo dei browser web. Molti sviluppatori di siti conformi agli standard hanno da tempo iniziato la campagna "visualizzabile con ogni browser" in modo da incoraggiare gli altri sviluppatori a creare siti compatibili con gli standard ufficiali, e non con quelli dei vari browser. </p><p>A partire dal <a href="/wiki/2005" title="2005">2005</a>, ci sono stati molti più siti web standard che in qualunque altro momento della storia del web. Continuano però a esserci molti siti con vecchio codice <a href="/wiki/JavaScript" title="JavaScript">JavaScript</a> che tende a bloccare browser che non siano Internet Explorer o Netscape Navigator. Questo è dovuto fondamentalmente al fatto che molti sviluppatori web di scarsa esperienza copiano e incollano codice da altri siti senza sapere ciò che stanno facendo. </p><p>Il peggior effetto dello spoofing è il fatto che la stima di utilizzo di Internet Explorer, il browser con la stringa più spesso copiata, è molto probabilmente esagerata rispetto al reale utilizzo del programma, mentre gli altri browser hanno una stima inferiore a quella reale. </p> <div class="mw-heading mw-heading2"><h2 id="Esempi_di_stringhe_di_user_agents">Esempi di stringhe di user agents</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=User_agent&veaction=edit&section=2" title="Modifica la sezione Esempi di stringhe di user agents" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=User_agent&action=edit&section=2" title="Edit section's source code: Esempi di stringhe di user agents"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Versioni di <a href="/wiki/Internet_Explorer" title="Internet Explorer">Internet Explorer</a>: </p> <ul><li>1.0 su <a href="/wiki/Windows_95" title="Windows 95">Windows 95</a> - <code>Microsoft Internet Explorer/4.0b1 (Windows 95)</code></li> <li>1.5 su <a href="/wiki/Windows_NT" title="Windows NT">Windows NT</a> - <code>Mozilla/1.22 (compatible;
