Title basically says it all. If I make an HTTP request in ComputerCraft, how can I get any headers that it returns such as the Location header for 301 redirects, the content length, and so on.

handle.getResponseCode()

As far as I know, getResponseCode() only returns the HTTP status code such as 200 OK or 301 Moved Permanently, but doesn't display the rest of the response headers.

In that case, there is no way to get any other response header.

I've got a memory that the betas for CC 1.76 can do some extra stuff in this area? The http API isn't something I've put a lot of research into.

For content length, just do the following:

local f = http.get(url)
local length = #f.readAll()

f.readAll returns the text on the page you requested.

and "#" return the number of elements in an object.

I'd point out fs.getSize before such awkward workarounds.

It is for http requests, not for the filesystem.

So it is. Which makes your suggestion even worse, because now the content must be fetched a second time to do anything useful with it. At least suggest saving it to a separate string before finding the length!
