/*
* Reads an entry from an input stream. A typical entry looks like this:
* http://google.com/foo
* GET
* 2
* Accept-Language: fr-CA
* Accept-Charset: UTF-8
* HTTP/1.1 200 OK
* 3
* Content-Type: image/png
* Content-Length: 100
* Cache-Control: max-age=600
*
* A typical HTTPS file looks like this:
* https://google.com/foo
* GET
* 2
* Accept-Language: fr-CA
* Accept-Charset: UTF-8
* HTTP/1.1 200 OK
* 3
* Content-Type: image/png
* Content-Length: 100
* Cache-Control: max-age=600
*
* AES_256_WITH_MD5
* 2
* base64-encoded peerCertificate[0]
* base64-encoded peerCertificate[1]
* -1
*
* The file is newline separated. The first two lines are the URL and
* the request method. Next is the number of HTTP Vary request header
* lines, followed by those lines.
*
* Next is the response status line, followed by the number of HTTP
* response header lines, followed by those lines.
*
* HTTPS responses also contain SSL session information. This begins
* with a blank line, and then a line containing the cipher suite. Next
* is the length of the peer certificate chain. These certificates are
* base64-encoded and appear each on their own line. The next line
* contains the length of the local certificate chain. These
* certificates are also base64-encoded and appear each on their own
* line. A length of -1 is used to encode a null array.
