Hi Kulvinder,
I haven't been able to reproduce this issue. Can you post some sample
code so I can try to debug this on my end?
Did you try adding the following to your application config file:
<configuration>
<system.net>
<settings>
<httpWebRequest useUnsafeHeaderParsing="true" />
</settings>
</system.net>
</configuration>
Cheers,
Lane
