wget http method not supported

Question

I am trying to access the http server in an iPad app called "WiFi photo" from the command line using wget. It works with curl, and through firefox, but I am getting error 505 in wget.

How can I fix this error?

Output of commands I have tried

Error given by wget

mac:getphotos billy$ wget 10.0.2.34:15555

Can you also post the headers for wget? And why not just use curl? — Thilo

wget only supports HTTP/1.0. See the documentation, Does Wget understand HTTP/1.?:

Wget is an HTTP/1.0 client. But, since the HTTP/1.1 protocol was designed to fully support HTTP/1.0 clients, Wget interoperates with most HTTP/1.1 servers.

It appears that the HTTP server is refusing to communicate when Wget sends an HTTP 1.0 request (which I'm pretty sure violates the spec). Consider filing a bug with the developer of the app. Otherwise you'll need to use something else like curl that supports HTTP/1.1.

Since v1.13 in 2011 wget supports HTTP/1.1 (via) and has switched to it as default somewhere on the way to 2022 when this comment was written.
