Manage a website's web proxy

Put a domain behind Coritan's edge on its Proxy tab, then change its web proxy, point it at one of your servers or delete it.

A website's Proxy tab manages the web proxy for the domain itself, such as example.com. A web proxy receives the domain's traffic at Coritan's edge, applies HTTPS and the WAF, and forwards each request to your origin (How web proxies work). Web proxies for names under the domain, such as www.example.com, are in Edge Proxy and on the domain's WAF tab.

  • The domain is on your Websites list, registered with Coritan or with its DNS zone hosted here.
  • To send the domain to one of your servers, you need a server on your account with an address and a port.
  • Visitors reach the web proxy only when the domain resolves to Coritan's edge. When Coritan hosts the zone and the domain has no A, AAAA or CNAME record yet, the web proxy writes a proxied A or AAAA record for it. If the domain already has an A or AAAA record, turn Proxied on for it on the DNS tab.
  • When another provider hosts the DNS, point the domain at the edge there. The SSL tab shows the address when you choose HTTP validation (Issue a certificate with HTTP validation).

Send the domain to one of your servers

Section titled Send the domain to one of your servers
  1. In the dashboard, go to Websites, open the domain and select the Proxy tab.
  2. On the Connect to one of your servers card, choose the Server. The card shows the address and port that requests will go to.
  3. Leave Request a certificate automatically on, so Coritan issues a certificate for the domain.
  4. Select Connect domain.

The web proxy starts with Force HTTPS, WebSockets and Web application firewall on, and connects to the server over plain HTTP. If you have no server yet, the card shows Order server instead.

Forward the domain to any origin

Section titled Forward the domain to any origin
  1. On the Proxy tab, select New route….
  2. Enter the Origin host, an IP address or a hostname such as origin.example.net, and its Port.
  3. Choose the Origin protocol, and turn on Connect to the origin over TLS if the origin serves HTTPS on that port.
  4. Choose the switches and, under Advanced options, any path, header or extra origin settings. Create a web proxy describes each field.
  5. Select Create route.

The Origin card lists the web proxy's Origins, Origin protocol, Path, Custom headers, Limits and Status.

  • To change them, select Edit route…, make the changes and select Save changes. Change a web proxy's origin explains each field.
  • The Switches card turns Force HTTPS, WebSockets, Web application firewall, TLS to origin and PROXY protocol to origin on or off. Each switch saves as soon as you change it.
  • The Certificate card has Request certificate and Open SSL. The SSL tab shows the certificate the edge serves for the domain (How SSL/TLS certificates work).
  • Open in Edge Proxy opens the web proxy's own page, with its Redirects and Error page tabs. On a narrow screen, open the web proxy from Edge Proxy instead.

Repoint the domain at one of your servers

Section titled Repoint the domain at one of your servers
  1. On the Repoint at one of your servers card, choose the Server.
  2. Leave Request a certificate automatically on to request a new certificate at the same time.
  3. Select Repoint domain.

Repointing replaces only the origin host and port with the server's address and port. The switches, path settings, headers and any additional origins stay as they are.

Warning

Deleting the web proxy deletes its settings, its redirect rules and its custom error page. Visitors who reach the edge for the domain see an error page until the domain has a web proxy again or its DNS points elsewhere.

  1. On the Delete this proxy route card, select Delete route….
  2. Type the domain, such as example.com, to confirm.
  3. Select Delete route.

The domain's DNS records stay as they are. A proxied record keeps sending visitors to the edge, so turn Proxied off for the record on the DNS tab to send them straight to your address (Add, edit and delete DNS records). The certificate stays on the SSL tab.

Each change shows a confirmation, such as Route for example.com created., example.com now points at 203.0.113.10:8080. or Proxy route for example.com deleted.. The tab then shows the web proxy's origin, certificate and switches, or the two ways to create one.

A route for this domain already exists
The domain already has a web proxy that this tab does not show, such as the one a proxied A or AAAA record creates. Turn Proxied off for the domain's record on the DNS tab, create the web proxy, then turn Proxied on again. If the domain has no proxied record, contact support.
Domain route owned by another user
Another account has a web proxy for the domain. Contact support.
Server has no allocated IP/port. Ensure the server has an active allocation.
The server has no address and port yet. Wait until its setup finishes, or choose another server.
Unable to resolve hostname: origin.example.net
The origin host does not resolve in public DNS. Check its spelling, or enter the origin's IP address.
host targets a private or reserved network or resolved address targets a private or reserved network
The edge only forwards to public addresses. Enter the origin's public address.
The form refuses the origin host
The Origin host takes a hostname or an IP address only, with no https:// and no port. Create a web proxy lists the form's messages.
Visitors get a certificate warning
The certificate is not issued yet, or its issuance failed. Open the SSL tab to see why (Issue a certificate).
Visitors see an error page from Coritan
The edge cannot reach your origin. Troubleshoot proxies and join addresses covers each error.

The Proxy tab uses the web proxy API, which Create a web proxy and Change a web proxy's origin describe. To find the web proxy for a domain, list your web proxies and pick the one whose domain matches exactly:

Shell
curl "https://api.coritan.com/api/v1/proxy/routes?per_page=200" \
  -H "Authorization: Bearer $CORITAN_TOKEN"
