Technologies are disclosed herein for asynchronous distributed editing of a structured document, such as a trouble ticket. A document management service receives edits to the structured document. The edits to the structured document include data to be stored in fields of the structured document and information identifying the fields into which the data in the edits is to be stored. The edits are synchronized to other instances of the document management service. Edits to the structured document made at the other instances of the document management service are also received and stored. When a request is received for the structured document, the edits to the document made at the various instances of the document management service are sorted based upon the order in which they were created. The edits are applied in the sorted order to generate the structured document.

Distributed asynchronous document editing

When servers hosting a website are under some form of deployment activity (e.g., a software update being in mid-deployment), the resources requested may not be available from all servers hosting the website. In such mid-deployment edge cases, the server would return an error message in response to the request. According to an application employing redirect instructions via a load balancer, a redirect function (such as a Hypertext Transfer Protocol (HTTP) status code 302) may be configured to redirect a client request to the same location as an initial request, via a load balancer, in order to provide the client with multiple attempts of reaching an updated host (e.g., a server hosting a resource based on a recent deployment), without having to receive error codes or otherwise fail to receive the requested resource.

Supporting heterogeneous environments during code deployment

Techniques are described for updating resources provided to a user device, using subscription based polling. A user device may send initial requests for resource to a server, each initial request including a resource identifier and a subscriber identifier. In some cases, the subscriber identifier may uniquely identify the communication session. The server maintains subscription information correlated with the subscriber identifier, the subscription information listing which resources the user device has requested and which versions of the resources are currently available on the user device. Updates to the subscribed resources may then be provided to the user device in response to a request for updates that specifies the session identifier but that may not specify the particular subscribed resources.
