Issue/Introduction
We're running a Web Agent and when a user request an URL having Ajax
code executed in the page, then the browser gets freezing and nothing
seems on the Web Page.
As our development team member expressed, there are 2 problems at
the moment :
- Some calls are redirected to the wrong JSON file;
- Some calls end with a blank page in the browser;
Those problems are seen in Internet Explorer and Edge browser
only : Chrome an Firefox browsers work fine.
How can we fix this ?
Environment
Web Agent 12.52SP01CR09 build 2614 on Apache 2.2 on RedHat 6;
Cause
You need to implement WebAppClientResponse in order to make the Web
Agent behavior in sync with the ajax code flow.
From documentation :
Web Application Client Response Introduced
Some web applications use script engines, which execute in the
context of a Web browser, to request resources and display
content. Similar to requests standard web browsers send, the
requests originating from the script engine can trigger
Agent-generated behavior, such as HTTP redirects or challenges.
Unless properly integrated with the web application, this behavior
can result in the web application client reaching an indeterminate
state.
The web application client response (WebAppClientResponse) ACO
parameter lets you:
- Configure CA Single Sign-on to identify requests originating
from the script engine that is executing in the context of the
Web browser.
- Use a customized response to integrate CA Single
Sign-on-generated behavior, including a challenge, with the
functionality of the web application client.
- Configure the response format for requests from Web 2.0
resources (AJAX and other API-based calls) at the global level.
- Configure a global response to the web application clients to
reduce the need to configure request/responses at each Web Agent
level manually.

fine in Internet Explorer and Edge, but works fine in Chrome and
