public static org.w3c.dom.Element prepareDetailsElement(org.apache.commons.httpclient.HttpMethod method)

Build a "details" element that looks like this:

Parameters:

method -

Returns:

Throws:

java.io.IOException

replaceCRLFwithLWS

public static java.lang.String replaceCRLFwithLWS(java.lang.String header)

This method ensures that a header value containing CRLF does not mess up the HTTP request. Actually CRLF is the end-of-line marker for headers.

To do so, all CRLF followed by a non-whitespace character are replaced by CRLF HT.

This is possible because the Section 2.2 of HTTP standard (RFC2626) states that:

HTTP/1.1 header field values can be folded onto multiple lines if the continuation line begins with a space or horizontal tab. All linear white space, including folding, has the same semantics as SP. A recipient MAY replace any linear white space with a single SP before interpreting the field value or forwarding the message downstream.

LWS = [CRLF] 1*( SP | HT )

FYI, HttpClient 3.x.x does not check this.

Parameters:

header -

Returns:

the string properly ready to be used as an HTTP header field-content

requestToString

public static java.lang.String requestToString(org.apache.commons.httpclient.HttpMethod m)

responseToString

public static java.lang.String responseToString(org.apache.commons.httpclient.HttpMethod m)

isFaultOrFailure

public static int isFaultOrFailure(int s)

Parameters:

s, - the status code to test, must be in [400, 600[

Returns:

1 if fault, -1 if failure, 0 if undetermined
