Yeah probably it has something to do with all the initialization stuff...I just tried *not* using the Apache HttpClient, with the following code:
String myHttpsUrl = "https://mip.sunrise.ch";; URL url = new URL(myHttpsUrl); URLConnection urlConnection = url.openConnection(); BufferedReader br = new BufferedReader(new InputStreamReader(ucon.getInputStream())); String line; StringBuilder htmlContent = new StringBuilder(); while ((line = br.readLine()) != null) { htmlContent.append(line); } (I'm reading the whole content just to make sure my request has been executed and fetched..). Anyway....it seems much faster!! (first request around 2 seconds, compared to the HttpClient's 6, 10 or 20 seconds). However there is a problem: with the current https url it actually doesn't work (it worked for other https addresses). I get back the following error (with the url "https://mip.sunrise.ch";): java.io.IOException: SSL handshake failure: Failure in SSL library, usually a protocol error error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol (external/openssl/ssl/s23_clnt.c:585 0xaf589f78:0x00000000) at org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl.nativeconnect(Native Method) at org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl.startHandshake(OpenSSLSocketImpl.java:308) at org.apache.harmony.luni.internal.net.www.protocol.http.HttpConnection.getSecureSocket(HttpConnection.java:173) at org.apache.harmony.luni.internal.net.www.protocol.https.HttpsURLConnection$HttpsEngine.connect(HttpsURLConnection.java:408) at org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnection.sendRequest(HttpURLConnection.java:1227) at org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnection.doRequestInternal(HttpURLConnection.java:1554) at org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnection.doRequest(HttpURLConnection.java:1547) at org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1055) at org.apache.harmony.luni.internal.net.www.protocol.https.HttpsURLConnection.getInputStream(HttpsURLConnection.java:257) It seems like an ssl version error...mmmm.... Maybe I have to specify explicitly this version somewhere? Or maybe some certificates? :S If anyone has an idea please let me know :) Thanks everyone!
