  1. POObjective C - HTTP/0.9 response from GET using ASIHTTPRequest
    text
    copied!<p>I've started using ASIHTTPRequest in my iOS project to execute REST server method calls and so far have been very successful with it. I just have one strange intermittent problem. Very occasionally I get the following response from using [ASIHTTPRequest startAsynchronous] :</p> <p>HTTP/0.9 200 OK</p> <p>When this occurs my server method doesn't get called. Normally every method call returns with a response starting 'HTTP/1.1'. I'm using HTTPS with a GeoTrust/RapidSSL certificate to secure the connection. Interestingly I've found that I get the same 'HTTP/0.9 200 OK' response if I try to connect to the SSL port (443) but specifying 'http' as the protocol.</p> <p>Just to add more info - the problem mostly occurs after the app has been left idle for a period of time. E.g. request completes successfully, then leave app idle for a while, then on the next request the problem occurs then app continues to work fine.</p> <p>Can anybody shed some light on what might be occurring?</p> <p>Many thanks, Jonathan</p> <p>UPDATE : I've pasted below some debug information output by ASIHTTPRequest when the problem occurred :</p> <pre><code>2012-07-12 09:35:49.376 mytestapp[3038:18f07] [CONNECTION] Closing connection #13 because it has expired 2012-07-12 09:35:49.377 mytestapp[3038:18f07] [CONNECTION] Closing connection #14 because it has expired 2012-07-12 09:35:49.378 mytestapp[3038:18f07] [CONNECTION] Closing connection #15 because it has expired 2012-07-12 09:35:49.380 mytestapp[3038:18f07] [CONNECTION] Request #39 will use connection #16 2012-07-12 09:35:49.381 mytestapp[3038:18f07] [CONNECTION] Request #40 will use connection #17 2012-07-12 09:35:49.382 mytestapp[3038:18f07] [CONNECTION] Request #41 will use connection #18 2012-07-12 09:35:49.529 mytestapp[3038:18f07] [STATUS] Request &lt;ASIHTTPRequest: 0x88a1e00&gt; finished downloading data (0 bytes) 2012-07-12 09:35:49.529 mytestapp[3038:18f07] [STATUS] Request &lt;ASIHTTPRequest: 0x88a1e00&gt; received response headers 2012-07-12 09:35:49.530 mytestapp[3038:18f07] [AUTH] Request &lt;ASIHTTPRequest: 0x88a1e00&gt; has passed Basic authentication 2012-07-12 09:35:49.530 mytestapp[3038:18f07] [CONNECTION] Got no keep-alive header, will keep this connection open for 60.000000 seconds 2012-07-12 09:35:49.530 mytestapp[3038:18f07] [CONNECTION] Request #41 finished using connection #18 2012-07-12 09:35:49.531 mytestapp[3038:18f07] [STATUS] Request finished: &lt;ASIHTTPRequest: 0x88a1e00&gt; 2012-07-12 09:35:49.531 mytestapp[3038:15803] responseHeaders={ } 2012-07-12 09:35:49.531 mytestapp[3038:18f07] [STATUS] Request cancelled: &lt;ASIHTTPRequest: 0x88a1e00&gt; 2012-07-12 09:35:49.532 mytestapp[3038:18f07] [STATUS] Request cancelled: &lt;ASIHTTPRequest: 0x88a0200&gt; 2012-07-12 09:35:49.532 mytestapp[3038:18f07] [STATUS] Request &lt;ASIHTTPRequest: 0x88a0200&gt;: Cancelled 2012-07-12 09:35:49.532 mytestapp[3038:18f07] [CONNECTION] Request #39 failed and will invalidate connection #16 2012-07-12 09:35:49.533 mytestapp[3038:18f07] [STATUS] Request cancelled: &lt;ASIHTTPRequest: 0x88a0a00&gt; 2012-07-12 09:35:49.533 mytestapp[3038:18f07] [STATUS] Request &lt;ASIHTTPRequest: 0x88a0a00&gt;: Cancelled 2012-07-12 09:35:49.533 mytestapp[3038:18f07] [CONNECTION] Request #40 failed and will invalidate connection #17 </code></pre>
