Hey everyone,<br />
<br />
I have an application hosted on Server 2008 that keeps throwing the following error when accessed:<br />
<br />
Data: HTTP/1.1 503 Service Unavailable\r\nContent-Len<wbr />gth:62\r\n<wbr />Connection<wbr />: close\r\nCache-Control: no-cache,no-store\r\nPragm<wbr />a: no-cache\r\n\r\n&lt;html&gt;&lt;bod<wbr />y&gt;&lt;b&gt;Http/<wbr />1.1 Service Unavailable&lt;/b&gt;&lt;/body&gt; &lt;/html&gt;<br />
--------------------------<wbr />-<br />
<br />
I searched around the net and I see that this normally relates to something server side, but thus far I haven't seen any errors in the IIS logs, nor any issues with the IIS config itself. &nbsp;Any ideas of what else I could check? &nbsp;Also, is there any possibility that the issue could be on the client side?<br />
<br />
Thanks
