A small syntax change. 

The following rule worked for me.

 

if(REGEX(URLfield__c,"^((http|https)://)??(www[.])??([a-zA-Z0-9]|-)+?([.][a-zA-Z0-9(-|/|=|?)??]+?)+?$"),false,true)

 

Hope this helps.

Can you give an example of how the URL looks like?

Following REGEX can be used for a website address.

^((http|https)://)??(www[.])??([a-zA-Z0-9]|-)+?([.][a-zA-Z0-9(-|/|=|?)??]+?)+?$

Hi Sathish,
Please refer the below logic for validation rule, please let me know anything wrong,

Why use the IF function if REGEX already returns a boolean value?

Here is the result of using the following formula: if(REGEX("^((http|https)://)??(www[.])??([a-zA-Z0-9]|-)+?([.][a-zA-Z0-9(-|/|=|?)??]+?)+?$",URLfield__c),false,true)
 

Some seemingly incorrect values are still accepted (e.g., http://www.gfh.") but most of it is okay.

I was having some troubles with the accepted solution above.

This worked best for me, with trailing slashes, and things with query params and fragments. e.g. https://wwww.classpack.webnode.es/ciao/m?coa=cia&ci=boa#example 
^((http|https)://)??(www.)??([a-zA-Z0-9-])+?(.??[a-zA-Z0-9]+?[-&#/?=]??)+?$
What I find offputting is that the proposed solutions works perfectly in regex101 with Java flavor, but wouldn't work in Salesforce.

Another problem that's not supposed to be solved with regular expressions...
oscar clarkoscar clark
Here is a regular expression for validating URLs:
^(https?|ftp)://(-\.)?([^\s/?\.#-]+\.?)+([^\s]*)?$
This regular expression allows URLs starting with either "http", "https", or "ftp", and checks for valid domain names as the gbwa.download is for GB whatsapp (https://gbwa.download/) and any additional path or query parameters. Note that this regular expression is not foolproof and may not catch all variations of valid URLs.
In terms of writing a validation rule for a specific programming language, it will depend on the language you are using. In general, you can use the regular expression above and apply it to the input using the language's regular expression matching function. For example, in JavaScript:
const urlRegex = /^(https?|ftp)://(-\.)?([^\s/?\.#-]+\.?)+([^\s]*)?$/;

function validateUrl(url) {
  return urlRegex.test(url);
}

In this example, validateUrl is a function that takes a string input url and returns a boolean indicating whether the input matches the URL regular expression.

One way to validate a URL is by using regular expressions. Here is a sample regular expression string for a URL:
^(https?|ftp)://[^\s/$.?#].[^\s]*$
This regular expression will match URLs that start with "http://", "https://", or "ftp://", followed by any characters that are not whitespace, "/", "?", "#", or ".". This will ensure that the URL is properly formed and does not contain any invalid characters.
