My Struts, Hibernate app (Appfuse based on JBoss with Tomcat plugin) has developed a really weird bug and I have no idea after a day of searching of how to track down the problem.
It seems that any request I make, be it a GET or a POST, is somehow followed up by three GET requests for the same action. Generally for GET requests this doesn't seem to break anything (although of course three times the network traffic is less than ideal). If the request happens to be a POST from a form submission however the thing tends to fall over from the subsequent GET posts. I have no idea why the browser is sending these extra requests. Nothing in the page contents or headers seems to be likely to cause this. I put a little proxy server I have between my browser and the app to see what happens. The headers and responses are : ====================================================== http://localhost/127.0.0.1:80 ====================================================== GET /portal/gateway.do HTTP/1.0 Host: localhost User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6 Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q= 0.8,image/png,*/*;q=0.5 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Proxy-Connection: keep-alive Cookie: JSESSIONID=38C8A3C4B5FED782C162C0326A38EBAE ====================================================== HTTP/1.1 200 OK Date: Fri, 30 Dec 2005 07:16:12 GMT Server: Apache/1.3.31 (Win32) PHP/4.3.4 mod_jk/1.2.0 Expires: Thu, 01 Jan 1970 00:00:00 GMT Pragma: No-cache Cache-Control: no-cache,no-store,max-age=0 Connection: close Content-Type: text/html;charset=ISO-8859-1 Content-Length: 16560 . . . Now the above looks OK. The page renders up on the browser without a problem This is followed immediately however by three identical requests like this: ====================================================== http://localhost/127.0.0.1:80 ====================================================== GET /portal/gateway.do HTTP/1.0 Host: localhost User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6 Accept: image/png,*/*;q=0.5 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Proxy-Connection: keep-alive Referer: http://localhost/portal/gateway.do Cookie: JSESSIONID=38C8A3C4B5FED782C162C0326A38EBAE ====================================================== HTTP/1.1 200 OK Date: Fri, 30 Dec 2005 07:16:12 GMT Server: Apache/1.3.31 (Win32) PHP/4.3.4 mod_jk/1.2.0 Expires: Thu, 01 Jan 1970 00:00:00 GMT Pragma: No-cache Cache-Control: no-cache,no-store,max-age=0 Connection: close Content-Type: text/html;charset=ISO-8859-1 Content-Length: 16560 The only differences I can see between the initial Get and the following ones are: Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q= 0.8,image/png,*/*;q=0.5 Versus Accept: image/png,*/*;q=0.5 and the three bogus requests have the line Referer: http://localhost/portal/gateway.do I'm wondering if anyone out there in list land has come across a problem with similar symptoms?
