Website returns 200 OK but only 1 byte of content in Firefox and Edge on Windows 11

I'm experiencing a very strange issue where a specific website, www.trysuri.com, returns a 200 OK status code but only a single byte of content. This happens in both Firefox and Edge on my Windows 11 laptop. The website works perfectly fine on my phone and work computer (over the same WiFi network), so the issue is definitely isolated to my machine.

So far, I've:

No luck! The website still loads completely blank.

One thing I did notice was that when checking the Windows Defender Firewall with Advanced Security app, Firefox was showing as TCP & UDP being blocked, but disabling the rule for Firefox did not resolve the issue. I didn't think it would, because other websites work fine, even with this blocked rule.

Below are the raw response headers

Note content-length: 1 despite the 200 OK. Seems a bit weird.

Now THIS looks like a proper response. So why can't I access it via the browser? I'm losing my mind here!

If the web server says that the content length is 1, with the header:

 content-length: 1

Then any sane browser will simply do a malloc() for one byte, and load one byte of the output in the buffer.

You can't blame the browser for doing what the server claims is right.

Note that there is a difference between the HTTP/1.1 and HTTP/2 protocol. The HTTP/2 handler specifies that the output is 1 byte, while the HTTP/1.1 protocol says it's 0 byte (streaming). This can be checked by comparing the output headers of curl and wget (wget does not support http/2).

wget headers:

HTTP/1.1 302 Found
Date: Tue, 11 Feb 2025 19:25:36 GMT
Content-Length: 0
Connection: keep-alive
Location: https://www.trysuri.com/em-cgi/btag/
Cache-Control: public, must-revalidate, proxy-revalidate, max-age=3600
Server: cloudflare

It seems there is a subtle difference in the web app that translates to 0 bytes content-length in HTTP/1.1 and 1 byte content-length in HTTP/2.

Depending on the preferred protocol by the browser / client this will lead to the client discarding the content (reading only one byte) or streaming the content.

Also note that the CDN's in use might be the problem (cloudflare and/or Edgemesh).

In short: the clients are not the problem, the servers are.

Steps to follow

  • test without CDN(s)
  • test using just HTTP/1.1
  • test to see if shopify is the problem, or a backend.
