Hi Naama,
The sap.com~tc~sec~ume~logon~ui.war file is not an APC, how do you get portalRequest and where are you referring this to be used.. in JSP??
portalRequest.getServletResponse(false).addHeader("X-UA-Compatible", "IE=Edge");
In case you are referring response object in JSP, I've never found that as useful in adding the above as <meta> tag during runtime. Did you ever implemented this and successful? Can you please share me the code snippet or a case study?
Thanks, MS
