/**
* Reads an entry from an input stream. A typical entry looks like this:
*
* <pre>{@code
* 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
* }</pre>
*
* <p>A typical HTTPS file looks like this:
*
* <pre>{@code
* 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
* }</pre>
*
* 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.
*
* <p>Next is the response status line, followed by the number of HTTP response header lines,
* followed by those lines.
*
* <p>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.
