A method and arrangement ( 100 ) for impermanent connectivity between a client unit ( 110 ) and a server ( 120 ) in a network, comprising: at the client unit, a client proxy function ( 114 ) for receiving information from/for a client application ( 112 ), for storing said information, and for relaying said information between the client unit and the server when a connectivity link ( 130 ) therebetween is established. The arrangement may further comprise a server proxy function ( 124 ), and a messaging subsystem ( 116, 122 ). The information may be SMTP, POP3, HTTP or FTP information. An FTP file ‘GET’ command may be performed by, in response to the ‘GET’ command, writing a local file at the client unit having a unique signature, and when the connectivity link is established, obtaining the requested file from the server, finding the file at the client unit having the unique signature, and over-writing the found file with the obtained file. This provides the advantages that: client application code does not have to be modified operation is largely invisible to the client.
