## Abstract

Described herein are enhancements for operating content nodes in a content delivery network. In at least one implementation, a content node deploys a request handler configuration and a key-value object, wherein the key-value object includes one or more key-value pairs and wherein the request handler configuration calls, in response to a content request from an end user device, the key-value object using a key associated with the content request and the key-value object returns a value associated with the key. The content node further obtains a request to modify the key-value object, identifies a modification to the key-value object based on the command, and updates the key-value object with the modification.

## Claims

### Claim 1

A method of managing key-value objects in a content node of a content delivery network, the method comprising:
utilizing a request handler configuration language to deploy a request handler configuration and a key-value object, wherein the key-value object includes one or more key-value pairs and wherein the request handler configuration calls, in response to a content request from an end user device, the key-value object using a key associated with the content request and the key-value object returns a value associated with the key;
obtaining a command to modify the key-value object;
in response to the command, identifying a modification to the key-value object based on the command; and
updating the key-value object with the modification without updating the request handler configuration.

### Claim 2 (depends on 1)

The method of claim 1, wherein the request handler configuration comprises a Varnish configuration language (VCL) configuration.

### Claim 3 (depends on 1)

The method of claim 1, wherein the modification to the key-value object comprises a replacement modification to replace a key-value pair in the one or more key-value pairs with a second key-value pair.

### Claim 4 (depends on 1)

The method of claim 1, wherein the modification to the key-value object comprises an addition modification to add a key-value pair to the one or more key-value pairs.

### Claim 5 (depends on 1)

The method of claim 1, wherein the modification to the key-value object comprises a removal modification to remove a key-value pair from the one or more key-value pairs.

### Claim 6 (depends on 1)

The method of claim 1, wherein obtaining the command to modify the key-value object comprises receiving, from a management system, the command to modify the key-value object.

### Claim 7 (depends on 6)

The method of claim 6, wherein the command to modify the key-value object comprises an application program interface (API) command to modify the key-value object.

### Claim 8 (depends on 1)

The method of claim 1, wherein the one or more key-value pairs comprise one or more country code to domain pairs.

### Claim 9

A content node comprising:
one or more non-transitory computer readable storage media;
a processing system communicatively coupled to the one or more non-transitory computer readable storage media;
processing instructions stored on the one or more non-transitory computer readable storage media that manage key-value objects for the content node that, when read and executed by the processing system, direct the processing system to:
utilize a request handler configuration language to deploy a request handler configuration and a key-value object, wherein the key-value object includes one or more key-value pairs and wherein the request handler configuration calls, in response to a content request from an end user device, the key-value object using a key associated with the content request and the key-value object returns a value associated with the key;
obtain a command to modify the key-value object;
in response to the command, identify a modification to the key-value object based on the command; and
update the key-value object with the modification without updating the request handler configuration.

### Claim 10 (depends on 9)

The content node of claim 9, wherein the request handler configuration comprises a Varnish configuration language (VCL) configuration.

### Claim 11 (depends on 9)

The content node of claim 9, wherein the modification to the key-value object comprises a replacement modification to replace a key-value pair in the one or more key-value pairs with a second key-value pair.

### Claim 12 (depends on 9)

The content node of claim 9, wherein the modification to the key-value object comprises an addition modification to add a key-value pair to the one or more key-value pairs.

### Claim 13 (depends on 9)

The content node of claim 9, wherein the modification to the key-value object comprises a removal modification to remove a key-value pair from the one or more key-value pairs.

### Claim 14 (depends on 9)

The content node of claim 9, wherein the processing instructions to obtain the command to modify the key-value object direct the processing system to receive from a management system, the command to modify the key-value object.

### Claim 15 (depends on 14)

The content node of claim 14, wherein the command to modify the key-value object comprises an application program interface (API) command to modify the key-value object.

### Claim 16 (depends on 9)

The content node of claim 9, wherein the one or more key-value pairs comprise one or more country code to domain pairs.

### Claim 17

An apparatus comprising:
one or more non-transitory computer readable storage media;
processing instructions stored on the one or more non-transitory computer readable storage media that manage key-value objects for the content node that, when read and executed by a processing system, direct the processing system to:
utilize a request handler configuration language to deploy a request handler configuration and a key-value object, wherein the key-value object includes one or more key-value pairs and wherein the request handler configuration calls, in response to a content request from an end user device, the key-value object using a key associated with the content request and the key-value object returns a value associated with the key;
obtain a command to modify the key-value object;
in response to the command, identify a modification to the key-value object based on the command; and
update the key-value object with the modification without updating the request handler configuration.

### Claim 18 (depends on 17)

The apparatus of claim 17, wherein the modification to the key-value object comprises a replacement modification to replace a key-value pair in the one or more key-value pairs with a second key-value pair.

### Claim 19 (depends on 17)

The apparatus of claim 17, wherein the modification to the key-value object comprises an addition modification to add a key-value pair to the one or more key-value pairs.

### Claim 20 (depends on 17)

The apparatus of claim 17, wherein the modification to the key-value object comprises a removal modification to remove a key-value pair from the one or more key-value pairs.
