Add preprocessor define QHTTPSERVER_EXPORT in the solution files to fix windows build.
Fix build for Qt4. No QStringLiteral there.
Try to uniform to a single coding convention/style. 2x spaces to 4x spaces. Add qWarning() to situations where nothing is done while still nothing is reported back to the caller. Id like to see these functions return bool.
Fix Date header to always use month and day names in english. QDateTime::toString uses the os/region language and does not conform to the RFC spec.
Improve .pro files: Dont define version on windows, it does <lib>0.dll which is not wanted on windows. Add windows d postfix to debug dlls. Make other projects link to correct lib. I could not get qmake to realise that tests and examples depend on the main library, so the first build at lest in visual studio will fail as the lib is not yet there.
Remove not needed include path from tests, also removes accidental tabs from previous commit.
Fix also mac and others to have version define.
