Hi All,
I have an ARR installed on IIS 8.5 acting as a reverse proxy for two web servers on backend for ASP.NET 4.0 applications. The application works fine when accessed directly via browser to application server. But while using ARR the application , the application
behaves strange in case of postback. I am using AJAX enabled updatepanel for asyncrhonous postback on master page for menu. Now, while browsing the application through ARR, the application randomly gives 502.3 error.
I drilled down further into the issue over internet and found this article suiting to my scenario:
https://forums.asp.net/t/1417101.aspx?Reverse+Proxy+server+that+prevents+loading+AJAX+Tool+control+related+scripts+in+the+browser+
It says:
"If Reverse Proxy server prevents loading Ajax Tool, I think it is not specific to the Ajax Control Toolkit. It is a generic incompatibility of Microsoft Ajax UpdatePanel with this type of scenario where the markup is rewritten on the fly and changes the
length of the rendered strings. This is the known issue."
I would like to confirm that if there is any work around for this issue now without modifying the source code.
I will just briefly list the list of specifications:
Windows server 2012
ARR 3.0
ASP.NET 4.0
Your suggestion is welcome.
Thanks in advance.
