(Updated Sept. 27, 2011, 9:12 p.m.) Review request for kdelibs. Changes ------- Found more proxy related issues and fixed those as well: * Remove support for 'PersistentProxyConnection' option since it serves no purpose other than causing unnecessary failures and bugs when using proxy servers. To see these problems, simply disable the 'Use persistent proxy conneciton' option in the proxy configuration dialog and use a proxy server, e.g. privoxy. * Cleaned up how m_request.isKeepAlive is used: - No point in calling httpCloseConnection based on the state of this flag in proceedUntilResponseHeader since sendQuery will always take care of that. - Do not reset m_request.ikeepAlive flag in httpCloseConnection. Otherwise, it will inadvertently set the flag to false since it gets called way too much. This flag now is initially set to true in resetSessionConfiguration and only updated based on how the remote sever responds. - If the server sends back a "keep-alive" header, but reports itself as a HTTP/1.0 server, make sure this flag is set to true. Description ------- This 5th patch in a serious of patches meant to improve proxy support in KDE deals with support at the kioslave level. More specifically the http ioslave. The patch is necessary to provide proper support for PAC script based proxy configuration. Namely allowing aleternate proxy servers to be specified and used as necessary. Here are the change this patch makes: * Add a new function in TCPSlaveBase to connect to the a remote server without automatically sending error notitification to the client. [NEW API] * Move the proxy related code from 'resetSessionSettings' to 'httpOpenConnection'. Proxy information will now be only set from 'setHost' and reset from 'reparseConfiguration' as it should have been from the beginning. No need to reparse proxy related information on every request. * Added a new variable, proxyUrls, to HTTPRequest to store the multiple proxy URLs obtained from the "ProxyUrls" meta-data. * Modified 'httpShouldCloseConnection' to account for multiple proxy addresses. * Modified 'sendQuery' to connect to the remote server before formatting the HTTP headers so that the headers can properly reflect the correct proxy settings.
