Bug 245247 – [SOUP] Too many redirections error loading PDF that works fine in Firefox

• Component: WebKit API
• Status: NEW

[Michael Catanzaro]

Try loading:

http://www.owenscorning.com/NetworkShare/Roofing/10013915-Deck-Defense-Technical-White-Paper-October-2011.pdf

The load will fail with the error "cannot follow more than 20 redirections," but the exact same URL works fine in Firefox. I've also frequently seen this error when opening attachments on this Bugzilla. Suspect we're doing something weird....

This is working for me on Safari Version 16.1 (18614.2.6.1.1) / macOS Ventura.
Does it still happening for you?

Do you have more details on error messages?

Yes.

"""
The precise error was: Load cannot follow more than 20 redirections
"""

It's coming from NetworkLoadChecker.cpp.

In the web inspector, I see only two resource loads attempted: about:blank, and network-error-symbolic.svg, which are both coming from the alternate HTML error page. It looks like not even a single request from the original load gets displayed in the web inspector, even though I checked the Preserve Logs option.

Well I tried adding some debug prints to see what's going on, but it works perfectly fine in my local build of WebKit main. The failures I'm seeing are with Tech Preview on 2.37.91. I won't believe it's actually fixed until I see it fixed in Tech Preview, though. :/

The url

I wonder if its a loop in between http and https.
