6. The proxy server system of claim 2 , wherein the first proxy link includes the first proxy string after a domain portion of the first proxy link.

7. The proxy server system of claim 1 , wherein the instructions, when executed by the one or more processors, cause the one or more processors to:

receive an override command including a third domain and a third proxy string;

generate a third mapping associating the third domain and the third proxy string; and

update the proxy mapping data to include the third mapping, wherein when the proxy mapping data includes an existing mapping corresponding to the third domain, the third mapping replaces the existing mapping.

8. The proxy server system of claim 1 , wherein the instructions, when executed by the one or more processors, cause the one or more processors to:

receive a reset command corresponding to one or more domains associated with the third-party network service; and

in response to the reset command, remove any mapping corresponding to the one or more domains from the proxy mapping data.

9. The proxy server system of claim 1 , wherein the instructions, when executed by the one or more processors, cause the one or more processors to:

receive a reconfigure command corresponding to one or more domains associated with the third-party network service; and

in response to the reconfigure command, for each mapping of the plurality of mappings that corresponds to the one or more domains, generate a new proxy string for the mapping and update the mapping with the new proxy string in the proxy mapping data.

10. The proxy server system of claim 1 , wherein the instructions, when executed by the one or more processors, cause the one or more processors to:

provide a link transformation service that:

(i) in response to a first transformation request that includes a submitted domain, obtains a first corresponding mapping from the proxy mapping data and provides a first transformation response that includes a proxy string of the first corresponding mapping; and

(ii) in response to a second transformation request that includes a submitted proxy string, obtains a second corresponding mapping from the proxy mapping data and provides a second transformation response that includes a domain of the second corresponding mapping.

11. The proxy server system of claim 1 , wherein the first proxy string encodes contextual data relating to at least one of a client device, the third-party network service, and a session between the client device and the third-party network service.

12. The proxy server system of claim 1 , wherein the first proxy string includes random characters.

13. The proxy server system of claim 1 , wherein the first proxy string includes sequential characters relative to a set of proxy strings.

14. The proxy server system of claim 1 , wherein the first proxy string includes at least one of predetermined prefix characters and predetermined suffix characters.

15. The proxy server system of claim 1 , wherein the first proxy string encodes security policy information.

16. A method implemented by one or more processors of a network computer system, the method comprising:

maintaining proxy mapping data including a plurality of mappings, each mapping associating a domain associated with a third-party network service and a proxy string;

generating, based on the proxy mapping data, a first native link that includes a domain associated with a third-party network service;

obtaining a resource including first native content from the third-party network service using the first native link;

identifying, in the first native content, a first embedded native link having a first domain associated with the third-party network service;

determining that the proxy mapping data does not include any mapping corresponding to the first domain;

generating a first mapping associating the first domain and a first proxy string; and

updating the proxy mapping data to include the first mapping.

17. The method of claim 16 , further comprising:

generating, based on the first embedded native link and the first mapping, a first proxy link that includes the first proxy string and a domain associated with a proxy server system;

generating configured content based on the first native content, wherein the configured content includes the first proxy link in replacement of the first embedded native link; and

providing the configured content to a client device.

18. The method of claim 16 , further comprising:
