For security reasons (I'm a developer) I do not have command line access to our Production servers where log files are written. I can, however access those log files over HTTP. Is there a utility in the manner of "tail -f" that can "follow" a plain text file using only HTTP?
You can do this if the HTTP server accepts requests to return parts of a resource. For example, if an HTTP request contains the header:
Range: bytes=-500
the response will contain the last 500 bytes of the resource. You can fetch that and then parse it into lines, etc. I don't know of any ready-made clients which will do this for you - I'd write a script to do the job.
You can use Hurl to experiment with headers (from publicly available resources).
