Notifications received from an email server can be stored and provided to a webclient upon subsequent communications from the webclient received at an HTTP server. Notifications stored in a database or a storage are retrieved and transmitted to the webclient by backup or alternate HTTP servers when the webclient requests service. An attachment received from a webclient for a message in composition can be saved by an HTTP server in a storage system so that a backup HTTP server can locate the attachment and provide the attachment to a messaging server when the user is ready to send the message.

Email webclient notification queuing

A token for a webclient in communication with an HTTP server to access an email system is stored at a database by the HTTP server. If the HTTP server is unexpectedly unavailable, a backup HTTP server that next interacts with the webclient can locate the token for the webclient using identifying information for the webclient to locate a record in the database containing the token. The backup HTTP server can then provide seamless access to the email system for the webclient despite the loss of connectivity to the initial HTTP server.

Persistent connections for email web applications

An attachment received from a webclient for a message in composition can be saved by an HTTP server in a storage system. Location information for the attachment can be stored in a database in a record associated with the webclient. If the HTTP server is unexpectedly unavailable, a backup HTTP server can locate the attachment using the record in the database and provide the attachment to a messaging server when the user is ready to send the message.
