Hi Nicolas, Late answer... The page on the Apache HTTP Client extension is this one: http://wiki.restlet.org/docs_2.0/13-restlet/28-restlet/75-restlet.html
As you can see in the linked Javadocs: http://www.restlet.org/documentation/2.0/jse/ext/org/restlet/ext/httpclient/HttpClientHelper.html there are various timeouts that can be set, however persistent connections can't be disabled. For connection timeout, this can be directly set via the Client#setConnectTimeout(int) method. The "socketTimeout" parameter is for reading/writing IO operations and "idleTimeout" is for persistent connections indeed. Note that version 2.1 has a much improved internal connector with persistent and non-persistent connections support, see the parameters: http://www.restlet.org/documentation/2.1/jee/engine/org/restlet/engine/connector/BaseHelper.html http://www.restlet.org/documentation/2.1/jee/engine/org/restlet/engine/connector/ConnectionHelper.html http://www.restlet.org/documentation/2.1/jee/engine/org/restlet/engine/connector/ClientConnectionHelper.html Also, in 2.1 the Client#connectTimeout property has been deprecated as it is hard to find compared to other connector parameters. Also, it isn't available for all connectors so it can be confusing to expose it. Use the new "socketConnectTimeoutMs" connector parameter instead or the general "maxIoIdleTimeMs" parameter for internal NIO connectors.

What I'm trying to do is: - disable persistant connections altogether. - set a specific timeout policy. Note: this is for the Apache httpclient connector, I've not tried with others. Connection Persistence: The only documentation I could find was: http://wiki.restlet.org/docs_2.0/13-restlet/27-restlet/324-restlet/130-restlet.html According to this, it appears that setting the context property "clientKeepAlive" to a specific value will disable connection persistence. The necessary value isn't clear, so I've tried "close", "off", "no" and "false". Whatever the configuration, the client's HTTP headers always contain a "Connection: Keep-Alive" entry. Is there a way to disable connection persistence, at least for the Apache httpclient connector? If so, I'd be grateful for any help, I've struggled with this for a while and am no further than when I started. Timeout handling This is a documentation issue more than an implementation one. I'd like to set a timeout for both socket opening and content retrieval - a query shouldn't take more than x seconds to be established, nor should it take more than y seconds to complete. Note that in my specific case, setting x and y to the same value is perfectly acceptable. Looking at the documentation (http://www.restlet.org/documentation/2.0/jse/ext/org/restlet/ext/httpclient/HttpClientHelper.html), I'm a bit confused. - socketTimeout is probably the variable I want to set for connection establishment. - I'm unsure what idleTimeout does. The documentation could describe both persistent connections timeout (if the connection hasn't been used for x ms, close it) or stalled connections. Either way, it doesn't look like what I'm looking for. There are no other timeout related configuration variables that I can see in the documentation. Am I missing or misunderstanding something? Thanks !
