normally large static files should not make it to the memory at all https://linux.die.net/man/2/sendfile

You could implement range support if your client supports them. I don't believe there is content-range support built into libevent, but I wrote my own (can't share, company IP) implementation for libevent. It wasn't that difficult to write. The RFC is pretty clear.

But there is a problem. I work on a "embedded" device. This device doesn't have so much memory (128MB) and the free memory available after a boot is about 30MB. When I send a file, I open it and put its content in a evbuffer. So, when the file is about a few kilobytes, it goes well but when I try to send a big file (a 70MB file for example), the device doesn't have the required memory and the sending fails. Is there a way to send a big file by chunks ? I saw on different documentations I can use the "Expect: 100-Continue" http/1.1 feature. I read a little bit the source code of libevent and it doesn't seem to implement this. Am I correct ? Do you know a guy who did this ? Perhaps there is a source code or a patch somewhere ? If not, I can work on this because I really need this "feature". Do you have some advices ? Perhaps you have already thought about how to implement this, haven't you ?
