ASP.NET - Redirecting wildcard sub-domain to folder (Plesk shared hosting)

mrcheez

I've recently moved my site from a dedicated VM to a shared hosting environment as I didn't need to have a dedicated machine.

The new environment has Odin Plesk 12, and most things are working fine except the wildcard redirect.

So for example I want:
test.mysite.com
to go to
www.mysite.com/member/test/

On my old server I had the following in my web.config which worked fine:

<rule name="my_subdomain" patternSyntax="ECMAScript" stopProcessing="true">
<match url="(.*)" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{HTTP_HOST}" pattern="^(?!www)(\w+)\.mysite\.com$" />
</conditions>
<action type="Redirect" url="http://www.mysite.com/member/{C:1}/&quot; appendQueryString="false" redirectType="Permanent" />
</rule>

but getting a DNS lookup failure on the new server with the same web.config setting.

I tried adding a .htaccess file to see if that would work, but to no avail.

Any ideas?


NOTE: Other rewritten urls are working fine, it's just the "www" replacement it can't handle.

Have you checked your DNS and done an nslookup?

Actually I've got an update.. I changed the DNS settings so I have the following now:

*.mysite.com (A record)
mysite.com (A record)
www.mysite.com (A record)

As this is how the dedicated server was setup. The addition of *.mysite.com seems to have resolved the DNS error, but now I'm just getting a default Plesk homepage screen.

When I ping blah.mysite.com I'm getting the correct IP address.


www.mysite.com and mysite.com work fine.

Something like this:

<rule name="CName to URL" stopProcessing="true">
    <match url=".*" />
    <conditions>
        <add input="{HTTP_HOST}" pattern="^(?!www)(.*)\.domain\.com$" />
    </conditions>
    <action type="Redirect" url="http://domain.com/{C:1}/{R:0}" />
</rule>

hmm nope the subdomain is still just showing a Plesk homepage

It must be something blocked by Plesk I guess.

I see the rule is called CNAME to URL ... do I need to create a CNAME like "*.mysite.com" ?

ok found out what's going on... it's a Plesk limitation for Windows only (predictably)

Here's someone with the same issue and eventually found a solution by adding a wildcard subdomain.

But wildcard subdomains aren't allowed in Plesk for Windows. When I manually created a "test.mysite.com" subdomain it correctly redirected.

Unfortunately I have about 5000 of these as each user on the site has their own subdomain, so I guess I'll have to change the code.

Dump plesk

You missed the part where I said it was shared hosting.. ain't got no choice and everything else on the server is working nicely

I wonder if I can do it programmatically instead

I checked the bindings I had on my old dedicated server for the site and they were:

http - mysite.com - Port 80 - IP Address: *
http - www.mysite.com - Port 80 - IP Address: *
http - - Port 80 - IP Address: *

I believe a sysadmin friend of mine set these up about 6 years ago, so is it possible that the 3rd "blank" entry is the solution I need to implement to get subdomain requests arriving to my site?

At the moment blah.mysite.com isn't hitting my web.config


I asked the new provider if they could make these changes in IIS for me, and they said yes, for a small fee, but I'd like to know if it will have the desired effect before I pay up!

mrcheez

anyone know if the 3rd binding I mentioned before is what I need to add to get wildcard subdomains working on my site?

so it's:
Type = http
Host Name = {blank}
Port = 80
IP Address = *

At the moment I have the "www" and "non-www" bindings.
