+
+Take a list of domains and probe for working http and https servers.
+
+## Introduction
+This is a customized version. Based on the original httprobe, several more features are added:
+* Supports scan IP segment as input
+* SUpports scanning specific ports within the IP / IP segment
+* Shows the title of the website (if exists)
+* Shows the status code of the respose header
+* Shows the content length of the respose data (if exists in reposnse header)
+* Shows whether the input ports are open
+
+## Original Repo:
+```
+https://github.com/tomnomnom/hacks
+https://github.com/tomnomnom/httprobe	
+```
+
+## Basic Usage
+
+httprobe accepts line-delimited domains on `stdin`:
+```
+echo [IP/IP segment] | ./[httprobe] [variables]
+cat [input file] | ./[httprobe] [variables]
+./[httprobe] -h
+```
+
+### Example Usage
+```
+echo 8.8.8.8/24 | ./httprobe -p 443,8080 -t 1000
+cat domains.txt | ./httprobe -p 8080 -t 500 -s
+```
+
+### Output
+```
+[ip],[url],[title],[status],[content-length],[port open/not]
+```
+
+## Others
+* If no content-length is found, shows -1
+* **Supports Chinese title**（using gbk for windows env, and utf-8 for mac/linux）
+* While using -s, by default the ':80' or ':443' will NOT be scanned
