Luca, thanks for the response. What you’re saying makes total sense, so no 
worries at all.

Tom, I won’t try to answer your questions, because I could only provide an 
educated guess at the answers :)

Just wanted to resurface this one. I posted it last week, but there hasn’t been 
any activity yet. I’d still love someone to take a look if they have a minute.

Kind regards,
Oliver

mod_proxy_fcgi bug using CONTENT_LENGTH and Transfer-Encoding chunked

[Oliver Dunk]

Hi,

I wanted to politely ask if anyone could take a look at 
https://bz.apache.org/bugzilla/show_bug.cgi?id=57087 
. This is an issue where 
CONTENT_LENGTH isn’t forwarded correctly when using Transfer-Encoding chunked. 
I feel uncomfortable bumping an issue in this mailing list, but it’s been open 
since 2014, and I’m not sure where else to ask.

In the real world, this is causing issues for me when uploading to a Nextcloud 
instance through macOS finder. Files are uploaded with a size of 0b and macOS 
shows an error. There’s an issue here which shows some instances of people 
running in to it: https://github.com/nextcloud/nextcloud-snap/issues/365 
.

For reference, the same issue was fixed in mod_fcgid a while back: 
https://bz.apache.org/bugzilla/show_bug.cgi?id=53332 
 and 
https://bz.apache.org/bugzilla/show_bug.cgi?id=50274 


It would be great if anyone could take a look at this, and see if it is 
feasible to fix in the near future. The only alternative I can think of is 
moving my installation away from mod_fcgid.

As a final note, I did consider the user mailing list, but I get the impression 
few developers look there. Hoping I made the right call.

Kind regards,
Oliver
