Check Server Headers Tool

This tool is for placement on my website to allow visitors to check server headers and verify HTTP status codes on their URLs.? I also need captcha to hold down abuse of the tool. See example of what I want here:? <[login to view URL]>? ## Deliverables I hope I have not left anything out; Simple interface? textarea? to insert a url, captcha and a button to activate the function and spot to display the returned http header information.? Please ask any questions that I may have overlooked.
