Hello i need a way to find out the host part of an url , i've tried
Request.Url.Host.Split('.')
but it doesn't work with url like this:
sub.sub.domain.com
or
www.domain.co.uk
since you can have a variable number of dots before and after the domain
i need to get only "domain"
Check out the second answer at Get just the domain name from a URL?
I checked the pastebin link; it's active. I didn't test the code myself, but if it outputs as he describes, you can .split() from there.
If you need to be totally flexibel, you need to make a list of all possible top-level-domains, and try to remove those, with dot, from the end of your string, resulting in
www.domain
or
sub.sub.domain
Then take the last characters after the last dot.

I am able to add the first CNAME without the underscore but when i try adding s1._subdomain, the underscore won't allow google domains to add it. It gives me an error saying the name is invalid. Any tips?
Should I change the domain provider or give up on SendGrid?
s1._domainkey should be the name (and not the value) of your CNAME without the last part of your own domain. For example, s1._domainkey.yourdomain.com should just be s1._domainkey.
Ran into this nearly 2 years later + posting back incase anyone else finds this - with Cloud DNS, you have to be really careful to add the . at the end. e.g. in sendgrid, it lists:
u28693559.wl060.sendgrid.net, which CloudDNS throws a wobbler at. However, if you add the . at the end it works.

I have the following url structure:
http://www.xyxyxyxyx.com/ShowProduct.aspx?ID=334
http://www.xyxyxyxyx.com/ShowProduct.aspx?ID=1094
and so on..
Recently I used IIS rewrite to rewrite this structure as
http://www.xyxyxyxyx.com/productcategory/334/my-product-url
http://www.xyxyxyxyx.com/productcategory/1094/some-other-product-url
and so on..
This works fine.
I want to create another rule so that if an invalid url requests comes with the following structure:
http://www.xyxyxyxyx.com/productcategory/ShowProduct.aspx?ID=334
the 'productcategory' part should be removed from the url and the url should look like
http://www.xyxyxyxyx.com/ShowProduct.aspx?ID=334
How do I write this rule?
It may vary depending on what you are using to apply the regex, but here's a basic one:
's|productcatgory/||'
If you want to make sure it also only does this when the xyxyxyxyx url is present, this should work:
's|^http://www\.xyxyxyxyx\.com/productcategory/|http://www\.xyxyxyxyx\.com/|'
Edit: Ah, so if productcategory could be any category, then you'll need to match around it, like so:
's|^http://www\.xyxyxyxyx\.com/.*/ShowProduct|http://www\.xyxyxyxyx\.com/ShowProduct|'
I am integrating with a system that creates part of a URL and I supply part of the URL.
I supply this:
http://myServer/gis/default.aspx?MAP_NAME=myMap
The system supplies this:
?type=mrolls&rolls='123','456'
(the "rolls" change depending on what the user chooses in the system)
so, my URL ends up looking like this:
http://myServer/gis/default.aspx?MAP_NAME=myMap?type=mrolls&rolls='123','456'
I need to get the rolls but when I try this in VB.Net:
Dim URL_ROLL As String = Request.QueryString("rolls")
I get an incorrect syntax error.
I think it's a combination of the 2nd question mark and the single quotes.
When the system is only passing one roll, it works, I can get the rolls from the URL
which looks like this:
http://myServer/gis/default.aspx?MAP_NAME=myMap?type=roll&roll=123
I asked them to change the format of the system's URL but they can't change it without affecting the rest of their users.
Can anyone give me some ideas on how to get the rolls from the URL with single quotes?
OK, I believe I've fixed my problem.
I used a regular expression to remove anything in the querystring that wasn't a number or a comma.
Thanks again for taking time to make your comments, it made me look at the problem from a different angle.
I've searched through all of the related topics here but none seems to answer my specific need. Here is the problem: Given a URL (sans protocol), I want to extract the subdomain portion, excluding www. The domain portion is always the same so I don't need to support all TLDs. Examples:
www.subdomain.domain.com should match subdomain
www.domain.com should match nothing
domain.com should match nothing
This is one of the many iterations I have tried:
[^(www\.)]\w+[^(\.domain\.com)]
Square brackets indicate character class and will remove all the order of otherwise special meaning of most characters.
You can try something like this instead:
((?:[^.](?<!www))+)\.domain\.com

To return what you're looking for instead of retrieving it through submatches:
((?:[^.](?<!www))+)(?=\.domain\.com)

The reason I'm asking is because IIS protects certain ASP.NET folders, like Bin, App_Data, App_Code, etc. Even if the URL does not map to an actual file system folder IIS rejects a URL with a path segment equal to one of the mentioned names.
This means I cannot have a route like this:
{controller}/{action}/{id}
... where id can be any string e.g.
Catalog/Product/Bin
So, instead of disabling this security measure I'm willing to change the route, using a suffix before the id, like these:
{controller}/{action}_{id} // e.g. Catalog/Product_Bin
{controller}/{action}/_{id} // e.g. Catalog/Product/_Bin
But these routes won't work if the id contains the new delimeter, _ in this case, e.g.
// These URL won't work (I get 404 response)
Catalog/Product_Bin_
Catalog/Product/_Bin_
Catalog/Product/__Bin
Why? I don't know, looks like a bug to me. How can I make these routes work, where id can be any string?
Ok, I have a definitive answer. Yes, this is a bug. However, at this point I regret to say we have no plans to fix it for a couple of reasons:
It's a breaking change and could be a very hard to notice one at that.
There's an easy workaround.
What you can do is change the URL to not have the underscore:
{controller}/{action}/_{id}
Then add a route constraint that requires that the ID parameter starts with an underscore character.
Then within your action method you trim off the underscore prefix from the id parameter. You could even write an action filter to do this for you if you liked. Sorry for the inconvenience.
You can use characters that are not allowed for a directory or file name like: *,?,:,",<,>,|.
With ASP.NET MVC if you look at the source they have a hard-coded value for the path separator (/) and to my knowledge cannot be changed.
