Built-in server

Item

Description

Port

Use this spin box to specify the port on which the built-in web server runs. By default this port is set to port 63342 through which RubyMine accepts connections from services. You can set the port number to any other value starting with 1024 and higher.

Can accept external connections If this checkbox is selected, then the files on the built-in server running on the specified port are accessible from another computer.
If this checkbox is cleared (by default), then the debugger listens only to local connections.
Allow unsigned requests

For security reasons, any request to a page on the built-in server from outside RubyMine is by default rejected and the authorization popup is displayed.

To access the requested page, click Copy authorization URL to clipboard and paste the generated token in the address bar of the browser.

However this behavior may be annoying, for example, it may block your debugging session if manual intervention is impossible. To suppress displaying the authorization popup, select the Allow unsigned requests checkbox.
