          org.melati.util.HttpHeader.HttpHeaderException

All Implemented Interfaces:

java.io.Serializable

Enclosing class:

HttpHeader

public static class HttpHeader.HttpHeaderException
extends java.lang.Exception

Exception detected in an HttpHeader.

We might want to declare some supertype as thrown or make this outer.

Header fields are usually obtained from servlet containers or similar after some processing. But its possible that some unusual client has sent something erroneous or just unusual that has not been filtered out earlier and causes an error here.

In general detecting such problems requires parsing. So although we could nearly always blame the caller we provide a service instead (as part of the contract).

We do sometime blame the caller because we assume that the caller has checked the next token type before some call. We do this by throwing an IllegalStateException instead.
