Now seems when uploading big file has problem in ssl. When I upload a
3K image file, it's ok. But when I upload a 35K image file. It
failed.
Ah, I see.
Is there any place to set the cache/buffer? Or I have to set
SSLSessionCache and SSLSessionCacheTimeout?
You should set the session cache anyway (failing to do so will result in a major drop in performance), but this should have no effect on the particular problem you're describing.
By the way, I don't understand why to use openssl s_client and issue a
GET request? I am uploading file. Isn't it a POST request? Can you
have a brief sample how to test?
It was unclear to me from your original message that *any* https was working, so I was trying to just give you the most basic test to try. I didn't realize you could upload small files successfully.
Did you turn on the ssl debug log and look at the spot in the large file upload where it failed?
