description = [[ Tries to find out the technology behind the target website. The script checks for certain defaults that might not have been changed, like common headers or URLs or HTML content. While the script does some guessing, note that overall there's no way to determine what technologies a given site is using. You can help improve this script by adding new entries to nselib/data/http-devframework-fingerprints.lua Each entry must have: * rapidDetect - Callback function that is called in the beginning of detection process. It takes the host and port of target website as arguments. * consumingDetect - Callback function that is called for each spidered page. It takes the body of the response (HTML code) and the requested path as arguments. Note that the consumingDetect callback will not take place only if rapid option is enabled. ]] --- -- @usage nmap -p80 --script http-devframework.nse -- -- @args http-errors.rapid boolean value that determines if a rapid detection -- should take place.
