dT cookie cause application error
Hi all,
I'm doing PoC using Mobile UEM solution with one of Telco in Thailand.
After instrumented Android app and installed Web Server and .NET agent in IIS, the application got hung during app start-up.
From what I found in session file, I noticed that for UEM capture some action with error as shown below.
Seems like problem is InvalidCaseException with Type casting during GetHttpHeader method.
May be cookies injected by UEM broke customer code. Hence error thrown and made application hung.
Here is a list of cookie that UEM add into HTTP Header according to document.
My question is , is there anyway to workaround this issue during PoC? Since customer use ISV to develop app, it is hard to ask them for code change especially for PoC.
Thank you

I'd start by configuring the Web Server sensor configuration on your Web Server Agent Group to capture all request headers (with a * wildcard) then re-produce the issue. Have a look at the headers to see if anything is in fact mangled. It looks from the stacktrace that it's trying to parse a Phone # from the cookie value, so see if it's there in a request that seems broken. Show the data to the developer and if they can confirm that it works unless DT is activated then open a support ticket.
Hope that helps,
