I'm using Apache 2.4.25 (httpd-2.4.25-win64-VC14.zip) under windows server 2016.
I have a 300MB zip file published in a directory. When a client tries to download it AND the client can download at a bandwidth speed slower than 20Mbps, the connection closes exactly at 130023424 bytes (124MB). It happens with firefox, chrome and wget.
I can reproduce the problem locally from linux and Mac with
| Code: | | wget --limit-rate=2000000 http://xxxx/yyy/filename.zip |
I have seen other three similar posts starting back to 2012:
https://www.apachelounge.com/viewtopic.php?p=23294
https://www.apachelounge.com/viewtopic.php?p=23437
https://www.apachelounge.com/viewtopic.php?p=25733
I applied the only workaround available: EnableSendfile On on the virtualhost, and it solved the problem.
But... I think it's a bug, and it should be solved in the code. |

I don't think it's a bug. As I mentioned in that second link it was just On by default in 2.2.
It's spelled out in the docs what it does and why
http://httpd.apache.org/docs/2.4/mod/core.html#enablesendfile
I think this is one of those "damned if I do, damned if I don't" things for Apache. Either way the default is someone is going to complain.
Grab a 2.2 (Apache Haus still has them for a short while longer) and try testing the feature by turning it off and downloading your 300mb file. If you get the entire file then maybe it is a bug. |
