I am looking for regex for simple URLs as
http://www.google.com
http://www.yahoo.in
http://www.example.eu
http://www.example.net
etc.
No subdirectories allowed. For example in this cases it must not validate http://www.google.com/, http://www.yahoo.in/mail.
Does anyone know any regex to do this?
I'm still a noob, but try this:
^http:\/\/[a-zA-Z0-9_\-]+\.[a-zA-Z0-9_\-]+\.[a-zA-Z0-9_\-]+$
This one should do:
^(https?:\/\/)?[0-9a-zA-Z]+\.[-_0-9a-zA-Z]+\.[0-9a-zA-Z]+$
This should work for URLs starting with http:// or https:// or without the protocol name.
The regex should also be used as case-insensitive. In that case, it can be shortened a bit:
^(https?:\/\/)?[0-9a-z]+\.[-_0-9a-z]+\.[0-9a-z]+$
If you don't care whether it is a valid url, you can use:
\S*www\.\S+
All the examples contain www. followed by a nonspace character, but that is unlikely to occur in a normal word.

I am having trouble with regex syntax in OWASP ZAP. I want to exclude from all scans all URLs that contain "web/lib". I've tried to add
^*web/lib*$
under Global Exclude URL option, but it didn't work. Please help - thanks a lot.
It's regex, if you're specifying wildcard you generally want period asterisk. You also probably need to escape the slash.

I am updating a website and need to forward url's with a specific pattern to a new page. I need to identify those URL's using a regex so only those get redirected.
An example of the URL I need to match on is;
/events/2894/an-event-page-title-123
I would not want to match on this URL
/events/example-page-123
The way to positively identify the URL's is to check for '/events/' followed by only numbers in the next section of the URL. there may be more or less than 4 numbers, but only ever numbers. As in the example, there is also
/^events\/([0-9]+)\/([a-z0-9_\.-]+)$/
Above is what I have tried which is probably very wrong as I am not very experienced with Regex (please stifle any laughter), but this is probably straightforward for someone.. many thanks in advance
^\/events\/([0-9]+)\/([a-z0-9_\.-]+)
Try this.See demo.Your regex was not matching because \ before `events was not matched.

I would use:
\/events\/\d+\/
which is /events/ followed by 1 or more digits, followed by /
I'm setting up URL Rewrite on an IIS and i need to match the following URLs using regex.
http://sub.mysite.com
sub.mysite.com
sub.mysite.com/
sub.mysite.com/Site1
sub.mysite.com/Site1/admin
but not:
sub.mysite.com/admin
sub.mysite.com/admin/somethingelse
sub.mysite.com/admin/admin
The site it self (sub.mysite.com) should not be "hardcoded" in the expression. Instead, it should be matched by something like .*.
I'm really blank on this one. I did find solutions to match the different URLs but once i try to combine them either none of them match or all of them do.
I hope someone can help me.
For your specific case, assuming you are matching the part after the domain (REQUEST_URI):
(?!/admin).*
(?!...) is a negative lookahead. I am not sure if it is supported in the IIS URL Rewrite engine. If not, a better approach would be to check for a complementary approach:
Or as #kirilloid said, just match /admin/? and discard (pay attention to slashes).
BTW. if you want to quickly test RegExps with a "visual" feedback, I highly recommend http://gskinner.com/RegExr/
([A-Za-z0-9]+.)+.com(?!/admin)/?([A-Za-z0-9]+/?)*
this should do the trick
We're using a proprietary tracking system that requires the use of regular expressions to load third party scripts on the URLs we specify.
I wanted to check the syntax of the regex we're using to see if it looks right.
To match the following URL
/products/18/indoor-posters
We are using this rule:
.*\/products\/18\/indoor-posters.*
Does this look right? Also, if there was a query parameter on the URL, would it still work? e.g.
/products/18/indoor-posters?someParam=someValue
There's another URL to match:
/products
The rule for this is:
.*\/products
Would this match correctly?
Well, "right" is a relative term. Usually, .* is not a good idea because it matches anything, even nothing. So while these regexes will all match your example strings, they'll also match much more. The question is: What are you using the regexes for?
If you only want to check whether those substrings are present anywhere in the string, then they are fine (but then you don't need regex anyway, just check for substrings).
If you want to somehow check whether it's a valid URL, then no, the regexes are not fine because they'd also match foo-bar!$%(§$§$/products/18/indoor-postersssssss)(/$%/§($/.
If you can be sure that you'll always get a correct URL as your input and just want to check whether they match you pattern, then I'd suggest
^.*\/products$
to match any URL that ends in /products, and
^.*\/products\/18\/indoor-posters(?:\?[\w-]+=[\w-]+)?$
to match a URL that ends in /products/18/indoor-posters with an optional ?name=value bit at the end, assuming only alphanumeric characters are legal for name and value.
I have a regex pattern for URL's that I use to check for links in a body of text. The only problem is that the pattern will match this link
stackoverflow.com
And this sentence
I'm a sentence.Next Sentence.
Obviously this would make sense because my pattern doesn't strong check .com, .co.uk, .com.au etc
I want it to match stackoverflow.com and not the latter.
As I'm no Regex expert, does anyone know of any good Regex patterns for checking for all types of URL's in a body text, while not matching the sentences like above?
If I have to strong check the domain extension, I suppose I'll have to settle.
Here's my pattern, but i don't think it help.
(([\w]+:)?\/\/)?(([\d\w]|%[a-fA-f\d]{2,2})+(:([\d\w]|%[a-fA-f\d]{2,2})+)?#)?([\d\w][-\d\w]{0,253}[\d\w]\.)+[\w]{2,4}(:[\d]+)?(\/([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)*(\?(&?([-+_~.\d\w]|%[a-fA-f\d]{2,2})=?)*)?(#([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)?
I would definitely suggest finding a working regex that someone else has made (which would probably include a strong check on the domain extension), but here is one possible way to just modify your existing regex.
It requires that you make the assumption that usually links will not mix case in the domain extension, for example you might see .COM or .com but probably not .Com, if you only match domain extensions that don't mix case then you would avoid matching most sentences.
In the middle of your regex you have [\w]{2,4}, try changing this to ([A-Z]{2,4}|[a-z]{2,4}) (or (?:[A-Z]{2,4}|[a-z]{2,4}) if you don't want a new captured group).
