timeout

The number of seconds of delay allowed between consecutive network packets received from the remote server. If the delay exceeds the timeout, the connection is dropped. The default is 120 seconds (2 minutes). This value is not the maximum time allowed for an entire transaction, but the delay between the packets. For example, the entire transaction can last 15 minutes, as long as at least one packet of data is received before each timeout period.

(timeout after interrupt) 

The timeout after interrupt value indicates how much time the Proxy Server has to continue writing a cache file after a client has aborted the transaction. In other words, if the Proxy Server has almost finished caching a document and the client aborts the connection, the server can continue caching the document until it reaches the timeout after interrupt value. 

The highest recommended timeout after interrupt value is 5 minutes. The default value is 15 seconds.
