Keeping original HTTP_HOST when Redirecting/Rewriting - nopcommerce

I am experiencing an issue with the IIS Rewrite Module and nopCommerce.
Situation:
I have several domains (Domain1.ca, Domain2.ca, etc.), each redirecting to a main domain (MainDomain.ca) at the Registrar level (using a CNAME record). Is it possible, using the IIS 8 Rewrite module, to retain the original HTTP_HOST value of the domain originally browsed to (Domain1.ca, Domain2.ca, etc.) instead of the redirected domain (MainDomain.ca)? I need this for the following reason:
In nopCommerce, each store corresponds to a unique domain (Store1 = Domain1.ca). To determine which store is active, nopCommerce obtains and resolves the "HTTP_HOST" value.
Unfortunately, since all domains get redirected to the main domain (MainDomain.ca), the original HTTP_HOST value (Domain1.ca) is lost. Therefore, not knowing which specific store needs to get activated, nopCommerce activates the first one in the list.
I assume that when a site has been redirected to, the original HTTP_HOST value is overwritten.
Does anyone have any experience with nopCommerce, HTTP_HOST, multi-store, domain redirection?

a CNAME does not perform any redirection.
A CNAME simply says that domain1.com will us ethe same dns records as domain2.com, aka it is an alias.
So if you are really are redirecting from your domain registrar then you are not using a CNAME record to do this. You must be using a REDIRECT service at the registrar, the most common one is an FRAME redirect, where they create a website for domain1.com and inside they put a frameset which points to domain2.com
I would suggest that remove this, and just use the CNAME only and then do the redirect at your webserver using URL REWRITE, this will then allow you to retain the original host name.

how to set a domain name for an iis hosed application which is mapped to a public ip

i have an application hosted on iis in one of the local system and it is mapped with public ip. Up to now we are using this by http://public-ip/application/login.aspx it is working perfectly, now we want to assign a domain name for the above url and have to access with that domain name from the outside also. can some one suggest what i have to do further.
Thanks
A few steps:
Buy the domain from any domain registrar. I personally use namcheap.com but you can use anyone you like.
Make sure you also purchase (if not included) the DNS management service (also called nameservers).
Once domain is purchased, login to your control panel and modify the DNS record.
Add an A Record for your domain, like this, where your IP is 111.111.111.111:
yourdomain.com. IN A 111.111.111.111
(Optional) you may want to add a CNAME record (an alias) so that www.yourdomain.com also works; that record would look like this:
www CNAME yourdomain.com.
Go to IIS, and change the name of the site to the domain name.
Wait for 30 - 40 minutes for the global DNS servers to propagate the changes.
Enjoy your new site.

What settings are required to put AWS CloudFront CDN in front of a squarespace website?

I had trouble getting AWS CloudFront to work with SquareSpace. Issues with forms not submitting and the site saying website expired. What are the settings that are needed to get CloudFront working with a Squarespace site?
This is definitely doable, considering I just set this up. Let me share the settings I used on Cloudfront, Squarespace, and Route53 to make it work. If you want to use a different DNS provide than AWS Route53, you should be able to adapt these settings. Keep in mind that this is not an e-commerce site, but a standard site with a blog, static pages, and forms. You can likely adapt these instructions for other issues as/if they come up.
Cloudfront (CDN)
To make this work, you need to create a Cloudfront Distribution for Web.
Origin Settings
Origin Domain Name should be set to ext-cust.squarespace.com. This is Squarespace's entry point for external domain names.
Origin Path can be left blank.
Origin ID is just the unique ID for this distribution and should auto-populate if you're on the distribution creation screen, or be fixed if you're editing Origin Settings later.
Origin Custom Headers do not need to be set.
Default Cache Behavior Settings / Behaviors
Path Patterns should be left at Default.
I have Viewer Protocol Policy set to Redirect HTTP to HTTPS. This dictates whether your site can use one or both of HTTP or HTTPS. I prefer to have all traffic routed securely, so I redirect all HTTP traffic to HTTPS. Note that you cannot do the reverse and redirect HTTPS to HTTP, as this will cause authentication issues (your browser doesn't want to expose what you thought was a secure connection).
Allowed HTTP Methods needs to be GET, HEAD, OPTIONS, PUT, POST, PATCH, DELETE. This is because forms (and other things such as comments, probably) use the POST HTTP method to work.
Cached HTTP Methods I left to just GET, HEAD. No need for anything else here.
Forward Headers needs to be set to All or Whitelist. Squarespace's entry point we mentioned earlier needs to know where what domain you're coming from to serve your site, so the Host header must be whitelisted, or allowed with everything else if set to All.
Object Caching, Minimum TTL, Maximum TTL, and Default TTL can all be left at their defaults.
Forward Cookies cookies is the missing component to get forms working. Either you can set this to All, or Whitelist. There are certain session variables that Squarespace uses for validation, security, and other utilities. I have added the following values to Whitelist Cookies: JSESSIONID, SS_MID, crumb, ss_cid, ss_cpvisit, ss_cvisit, test. Make sure to put each value on a separate line, without commas.
Forward Query Strings is set to True, as some Squarespace API calls use query strings so these must be passed along.
Smooth Streaming, Restrict Viewer Access, and Compress Objects Automatically can all be left at their default values, or chosen as required if you know you need them to be set differently.
Distribution Settings / General
Price Class and AWS WAF Web ACL can be left alone.
Alternate Domain Names should list your domain, and your domain with the www subdomain attached, e.g. example.com, www.example.com.
For SSL Certificate, please follow the tutorial here to upload your certificate to IAM if you haven't already, then refresh your certificates (there is a control next to the dropdown for this), select Custom SSL Certificate and select the one you've provisioned. This ensures that browsers recognize your SSL over HTTPS as valid. This is not necessary if you're not using HTTPS at all.
All following settings can be left at default, or chosen to meet your own specific requirements.
Route 53 (DNS)
You need to have a Hosted Zone set up for your domain (this is specific to Route 53 setup).
You need to set an A record to point to your Cloudfront distribution.
You should set a CNAME record for the www subdomain name pointing to your Cloudfront distribution, even if you don't plan on using it (later we'll go through setting Squarespace to only use the root domain by redirecting the www subdomain)
Squarespace
On your Squarespace site, you simply need to go to Settings->Domains->Connect a Third-Party Domain. Once there, enter your domain and continue. Under the domain's settings, you can uncheck Use WWW Prefix if you'd like people accessing your site from www.example.com to redirect to the root, example.com. I prefer this, but it's up to you. Under DNS Settings, the only value you need is CNAME that points to verify.squarespace.com. Add this CNAME record to your DNS settings on Route 53, or other DNS provider. It won't ever say that your connection has been fully completed since we're using a custom way of deploying, but that won't matter.
Your site should now be operating through Cloudfront pointing to your Squarespace deployment! Please note that DNS propogation takes time, so if you're unable to access the site, give it some time (up to several hours) to propogate.
Notes
I can't say exactly whether each and every one of the values set under Whitelist Cookies is necessary, but these are taken from using the Chrome Inspector to determine what cookies were present under the Cookie header in the request. Initially I tried to tell Cloudfront to whitelist the Cookie header itself, but it does not allow that (presumably because it wants you to use the cookie-specific whitelist). If your deployment is not working, see if there are more cookies being transmitted in your requests (under the Cookie header, the values you're looking for should look like my_cookie=somevalue;other_cookie=othervalue—my_cookie and other_cookie in my example are what you'd add to the whitelist).
The same procedure can be used to forward other headers entirely that may be needed via the Forward Headers whitelist. Simply inspect and see if there's something that looks like it might need to go through.
Remember, if you're not whitelisting a header or cookie, it's not getting to Squarespace. If you don't want to bother, or everything is effed (pardon my language), you can always set to allow all headers/cookies, although this adversely affects caching performance. So be conservative if you can.
Hope this helps!
Here are the settings to get CloudFront working with Squarespace!
Behaviours:
Allowed HTTP Methods Ensure that you select: GET, HEAD, OPTIONS, PUT, POST, PATCH, DELETE. Otherwise forms will not work:
Forward Headers: Select whitelist and choose 'Host'. Otherwise squarespace will not know which website they need to load up and you get the message 'Website has expired' or similar.
Origins:
Origin Domain Name set as: ext-cust.squarespace.com
Origin Protocol Policy Select HTTPS so that traffic between the CDN and the origin is secure too
General
Alternate Domain Names (CNAMEs) put both your www and none www addresses here and let Squarespace decide on if to direct www to root or vice-versa (.e.g example.com www.example.com)
You can now configure SSL on CloudFront
HTTPS You can now enforce HTTPS using a certificate for your site here rather than in Squarespace
Setting I'm unsure about still:
Forward Query Strings: recommended not for caching reasons but I think this could break things...
Route53
Create A records for www and root (e.g. example.com www.example.com) and set as an alias to your CloudFront distribution

DNS custom domain to subfolder

I have a SaaS app where every user has a personal subdomain: username.domain.com. Every user has a personal blog at username.domain.com/blog.
Now I want to accept custom domains, e.g. www.mycustomblog.com would be an alias for username.domain.com/blog.
If someone browses to www.mycustomblog.com/123, the page username.domain.com/blog/123 should be served.
However, I do NOT want a redirect. The user should still see www.mycustomblog.com/123in their address bar.
How can I achieve this behaviour? I have looked into Nginx reverse proxies, DNS CNAME records... but nothing seems to suit my needs. I can access both the custom domain DNS settings and all of the server's config files.
I think what you're looking for is a rewrite. However your described logic doesn't work:
www.mycustomblog.com -> username.domain.com/blog
appears to be missing a piece of identifying information on the left side. Perhaps www.mycustomblog.com/username? After that, it's just a matter of writing out the match/map statements to change the request to match what you've got on the server.

ASP.NET virtual subdomain via Rewrite

I'm going to make pages accessible by subdomains like below:
http://product12.domain.com instead of http://domain.com/?productid=12
How can I do that? is it possible to create subdomains programatically via ReWrite or RouteMap?
Subdomains, by definition, are part of the DNS. You'd have to create the appropriate subdomains within your domain management system. I may be wrong, but I don't think URL rewriting is supposed to be used for host redirection; you'd have to either set up routes to catch your query strings and redirect to another host, or potentially use IIS to do it.

How to change URL address in ASP.NET?

I have a business requirement, where i should show a different URL in the address bar from the actual. Say for ex: I have hosted my site at Hum.com. But for some users, this URL should show up as CP.com at the address bar? Is it even possible?
The only way to do this is if you control both domains, hum.com and cp.com and if you configure your web server to serve the same application for cp.com and hum.com.
If above is the case (you control both domains), you can simply redirect the users to the appropriate domain using Response.Redirect.
This is easily done in Apache via NameVirtualHosts and I am sure IIS offers the same functionality.
Yes this is possible, but it's generally done at the DNS level and not within the application itself. You want the IP address of Hum.com to resolve to the same IP address as CP.com. This is how hosting sites such as Google Sites generally work.
To do this you need to own the DNS entry for your vanity domain name (i.e. CP.com) and you need to ensure that the hosting site is capable of associating requests for CP.com with the hosted website.
This can be done by redirect.
if(fUserOfCP && !HttpContext.Current.Request.RawUrl.Contains("cp.com/")){
Responce.Redirect(
HttpContext.Current.Request.RawUrl.Replace("hum.com/", "cp.com/")
, true);
}
This code is the idea, probably is better to break the RawUrl, check and reconstruct it on the redirect to avoid the existing of host on file name.
Assume that both names belong to you, and you have setup correctly the dns.
Rewrite is not possible on host name if this is your first thoughts.
