Subject [jira] Commented: (GERONIMO-3839) some request headers may be added twice
Date Tue, 12 Feb 2008 10:51:09 GMT

    [ https://issues.apache.org/jira/browse/GERONIMO-3839?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12568046#action_12568046

Rick McGuire commented on GERONIMO-3839:
----------------------------------------

It seems like HttpRequestEncoder should be overriding those particular headers rather than
not adding them.  I agree there should be a single set, but it seems like the ones added by
the HttpRequestEncoder should be consider the "correct" set.

> Some request headers get special treatment by HttpRequestEncoder.  HttpRequestEncoder
does not make any effort in checking to see if they are present in the headers already.  As
a result, they may be added twice if one is not careful.  For example,
> - Content-Type & Content-Length are added by HttpRequestEncoder for POST requests,
and should not be added by callers.
> - Host & User-Agent are always added by HttpRequestEncoder, and should not be added
by callers as ordinary headers.
> Although one could argue that callers should not add these headers by hand, I think HttpRequestEncoder
still should ensure that they are not added twice.
