Issue/Introduction

After upgrading the url_response probe from 4.43 to 4.50, some of the URLs started to generate alarms with fault codes 23 and 61.

URL response for 'http://xxx.xxxxxxx.gxxxxx' failed. 23 Failed writing received data to disk/application

OR

URL response for 'http://sixxx.sxxxx.xxxxxxv.xxx' failed. 61 Unrecognized or bad HTTP Content or Transfer-Encoding

If the probe is downgraded, the problem doesn't occurs.

Environment

Release : 20.3

Component : UIM - URL_RESPONSE

Cause

This problem only occurs if the robot where the probe is deployed is a Windows box.

The Windows version of the probe is compiled with higher curl lib version (7.61.1) than Linux is compiled with (7.43.0).

That is the only difference.

The problem can not be reproduced if the probe is deployed on Linux.

Resolution

L2 created a testfix to resolve the issue.
