Last Modified Date of a file on a web site
html, http
Solution
Go to the website you want to know about, wait for it to fully load, then go to the address bar and write this:
javascript:alert(document.lastModified)
You'll get a popup that says when it was last modified.
Problem
Is there a way to get the Last-Modified-Date of a file on a Web Site? i.e. Here is an example file I have out there: http://www.ymcadetroit.org/atf/cf/%7B2101903E-A11A-4532-A64D-9D823368A605%7D/Birmingham_Youth_Sports_Parent_Manual.pdf
