ASM: Failed to convert character
Hello everyone, I have an application protected by ASM using charset UTF-8. What happens is that sometimes I get some false-positives because the user browser is not using the charset informed in the meta tag. For instance, in some tests using Chrome and having as input some strings like “weißbier” or “über” I have no problems, but when I use Internet Explorer 11, ASM blocks the request with this error. There is an article from Microsoft about this saying that IE does not always take the specified charset in the page but it might be overridden by OS settings: https://support.microsoft.com/en-us/help/928847/internet-explorer-uses-the-wrong-character-set-when-it-renders-an-html So my question is, how do you deal with this? I wouldn't like to disable this check in the Security Policy, any possible alternatives?
Domain was fixed in Internet Security on Internet Explorer (IE)
How it possible to edit the domain in Internet Security when it's prompt as this image below example image I has set the F5 APM to fixed the domain name, using Variable Resource Assign expr { "[mcget {session.ad.last.actualdomain}]\\[mcget {session.logon.last.username}]" } I try with Chrome, Firefox so it's work well, but in IE have fixed the Domain for each PC. For my guess, I think the behavior of Chrome and Firefox will be like Username : username Password : password after we input the information above the Variable Resource Assign will automatically add the domain to be the domain\username . On the other hand, the result of IE (that browser fix domain) will be like RINGWORLD\domain\username that will make authentication abort. My idea is to check the browser type, if the client use IE -> the F5 APM will remove the domain that fixed from the browser. Finally, I am not sure that it's possible to do it like this way or someone can give me a better solution. -F5 APM with Version 12.1.2 HF1 -IE Version 11 -F5 SSL VPN Thank you very much
