Definitely not the browser. Compression seems like the most likely culprit here.

I’m leaning towards the compressed response too. It can mess with the monitor's checks.

I feel like the Content-Type being "iso-8859-200" is a red flag. Could confuse the monitor.

I agree, but what about the chunked response? That might also lead to false positives.

This question is tricky. I think the response being compressed could cause issues.

Definitely sounds like a misconfiguration with the monitor itself.

A different browser won't fix this, that's for sure.

Surprised that the Content-Type could affect the monitor like that!

Chunked response, huh? Looks like the LTM Specialist has some troubleshooting to do.

Another browser? Nah, the monitor should work across all browsers.

Content-Type "iso-8859-200"? What is this, the 1990s?

Compressed response? Sounds like a job for the LTM Specialist!

The response is chunked. That's the issue.

I’m leaning towards the chunked response being the culprit, but I wish I had more clarity on how that impacts the monitor's status.

I feel like the Content-Type might not be the main issue, but I can't recall if it could lead to a false positive.

I think I saw a similar question where compression affected the monitor's ability to read the response correctly. Could that be it?

I remember something about how chunked responses can confuse monitors, but I'm not entirely sure if that's the issue here.

I've seen issues like this before where a caching or compression setting was causing the monitor to report the wrong status. I'll make sure to thoroughly investigate those areas.

Okay, let's see. If the end users can't access the website, but the monitor says it's up, that suggests the monitor is not accurately reflecting the actual user experience. I'll focus on the network and application-level factors that could be causing that discrepancy.

I'm a bit confused by the "iso-8859-200" Content-Type option. That doesn't seem like a standard encoding to me, so I'll probably rule that one out.
SE

I disagree, I think it's the compressed response causing issues.
DE
Delisa 10 months ago
It's probably the response is chunked.
JA

I think using another browser is a stretch. The monitor should work regardless of that.
TR

The response being chunked or compressed could definitely cause issues with the monitor. I'll need to look into those possibilities more closely.

Hmm, this looks like a tricky one. I'll need to carefully consider the options and think through the possible causes of the false positive.
