FEATURED COMPONENTS
First time here? Check out the FAQ!
I'm using ZK 5.0.3 Framework + IE 9 + Weblogic 10.3. On my UI, I get HTTP 501 service unimplemented error randomly. I've verified the code and nothing suspicious found. When I intercepted the HTTP messages between IE and Weblogic using Fiddler, found that there were garbage characters prepended to the POST method. Here's a sample intercepted RAW HTTP message sent by UI to backend.
ERROR : 22%3A0%2C%22LEFT%22%3A160%7D&CMD2=ONSCROLLPOS&UUID2=UQ0Q2R&DATA2=%7B%22TOP%22%3A0%2C%22LEFT%22%3A2948%7D&CMD3=ONCLICK&UUID3=UQ0Q1R&DATA3=%7B%22PAGEX%22%3A360%2C%22PAGEY%22%3A225%2C%22WHICH%22%3A1%2C%22X%22%3A5%2C%22Y%22%3A-3%7DPOST httpurl://192.168.4.169:7001/DPQA13/zkau HTTP/1.1 Accept: / Content-Type: application/x-www-form-urlencoded;charset=UTF-8 ZK-SID: 2331 Referer: httpurl://192.168.4.169:7001/DPQA13/DP/home.zul Accept-Language: en-in Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; BRI/2) Host: 192.168.4.169:7001 Content-Length: 136 Connection: Keep-Alive Pragma: no-cache Cookie: JSESSIONID=D9TTRnFR8DyWpGc84cQZxVW1Gx7K0Z14kKRKsDQmntr9zSkZtYk8!-1480174431

Interestingly, the ZK library has a retry mechanism which retries the HTTP communication if there's a 5xx error code. However, when it retries for the second time, it does send the correct HTTP method, no garbage characters prepended. Does anyone know how to solve this?
Hi, I have tried ZK 5.0.3 (zk-demo-5.0.3.zip)& ZK 6.5.2 (zk-sandbox-6.5.2.zip)+ IE 9 + Weblogic 10.3 with Window 7, using zksandbox War demo application, the application works fine, I didn't get 501 response, can you provide a War file that can reproduce the issue?
Hey samchuang, I really appreciate the efforts taken by you. Yesterday, we did narrow down the problem and found out the actual cause. We were using IE Version: 9.0.8112.16421 - Update Versions: 9.0.6 (KB2675157) which was producing this defect. We tried on another Windows machine with IE Version: 9.0.8112.16421 - Update Versions: 9.0.15 (KB2817183) and it ran smoothly. It was clear that the 9.0.6 had some problem and so we upgraded it with "Automatic Updates On". As it got upgraded to 9.0.15 (KB2817183), the problem disappeared.
