Method Detail

download

public void download(HttpURLConnection connection,
                     String fileName,
                     String originalURL)
              throws IOException

Downloads a file via the passed in connection, and detects URLs using the Sperowider pattern matching command embedded in the found file. That command would look like : // <spero-mongle><pattern>"((/[^"]+)|(http://[^"]+))"</pattern><group>1</group><replace-with>SperoDocRoot + "includes/headers/" + "${URL}"</replace-with></spero-mongle>

• pattern indicates how to find URLs
• group is the number of the matching group in the pattern that has the URL
• replace-with is a pattern to use to replace the found URL. $0 through $9 can be used, as well as {$url} to indicate the rectified form of the URL.
