Why won’t Google Chrome really or Firefox capture the network developer request of a form autopost

So imagine this code running on localhost:9080, the page does not render content but instead does a HTML auto post. But I like to use the network tab to see the HTML content rendered under the developer tools but the error I see under “Review or Source” is Could not Capture Data.

Ironically firefox does the same thing.

I was able to get the response data from cURL.

Why doesn’t google chrome allow me to see the content. I can seee the size, I thought it would have capture this. Especially in 2024, must be some kind of bug.

Are there other tools besides wireshark or fiddler that would allow me to see the data, maybe a chrome extension that will capture ALL data and not mangle what is actually download from the server.

so in in the network traces for Chrome I cannot see the source for this but would like to.

<form method="post" action="/Welcome/Login" target="_top">
<input type="hidden" name="ACTION" value="DISP_PAGE">
