Rewriting HTTP url to HTTPS using regular expression and javascript

Question

I\'m in a situation where I need to rewrite an url in javascript and switch it from http protocol to https.

I can match https urls with:

if(url.match(\'         


        

Answer 1

Cannot it be done by simply replacing the http string?

if(url.match('^http://')){
     url = url.replace("http://","https://")
}
