there 2 possibilities: 1)have checked , tested connection.

2)better don't set connection timeout,if setting chose maximum time,,because throws error,if server didn't response within given time.

so can use

httpurlconnection conn = (httpurlconnection) url.openconnection(); conn.setconnecttimeout(7000);

or can use

for (int retries = 0; retries < 3; retries++) { try {     final httpclient client = createhttpclientwithdefaultsocketfactory(null, null);     final httpresponse response = client.execute(get);     final int statuscode = response.getstatusline().getstatuscode();     if (statuscode != 200) {         throw new illegalstateexception("get request on '" + get.geturi().tostring() + "' resulted in " + statuscode);     } else {                         return response.getentity();     } } catch (final java.net.sockettimeoutexception e) {     // connection timed out...let's try again                      } }

hope helps you, enjoy code:)

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
