Hi. All. <div>Another big issue with http client within erlang distribution and ibrowse. That makes me start to wonder is ibrowse/http client really working?</div><div><br></div><div>Please try following url. </div><div><a href="http://www.cisworldwide.com/xweb/xweb_parser.php?premiumredirect=http%3A%2F%2Fwww.cisworldwide.com%2Fxweb%2Fpremiumsearches%2FxmlNewBackgroundSearch.php%3Fatype%3Dcaps%26fname%3Dscott%26middle_initial%3D%26lname%3Dzhang%26city%3D%26state%3D%26zip%3D%26client_reference%3Dplutux%40harbork.%26cisrestype%3Dunlimited_background&code=11111111&cemail=macromarship@gmail.com">http://www.cisworldwide.com/xweb/xweb_parser.php?premiumredirect=http%3A%2F%2Fwww.cisworldwide.com%2Fxweb%2Fpremiumsearches%2FxmlNewBackgroundSearch.php%3Fatype%3Dcaps%26fname%3Dscott%26middle_initial%3D%26lname%3Dzhang%26city%3D%26state%3D%26zip%3D%26client_reference%3Dplutux%40harbork.%26cisrestype%3Dunlimited_background&code=11111111&cemail=macromarship@gmail.com</a><br>
</div><div><br></div><div>it can be opened in firefox or IE or any browse and it returns search result of my name.</div><div><br></div><div>But whether I use http client or ibrowse, they never returns, just hang there, even I wait for 10 minutes. </div>
<div>I tried with http client/ibrowse to download <a href="http://www.google.com">www.google.com</a> or <a href="http://www.erlang.com">www.erlang.com</a>, they are working. But for this one. NO.</div><div><br></div><div>

<p>And based on my observation, ibrowse seems integrated a builtin loadbancer. Actually I didn't care this much. Use default http client or ibrowse is same to me. Just want to have a different try. BTW, if default http client is good enough, why these guys were trying to creating ibrowse?</p>
<p>If default http client can let me bind IP when I initial the http request, that will be perfect. </p><p></p><p>Thanks.</p><p>Regards.</p><p>Scott Zhang ( I should change my name. :) )</p><div><div></div><div class="Wj3C7c">

<br>
What do you mean with better http client library?<br>
Is it the http client included in the Erlang/OTP distribution you are<br>
referring to?<br>
In that case what problems have you had with that one?<br>
or what functions are you missing?<br>
<br>
I know that there are weaknesses in it but the functionality is more<br>
or less the same as Ibrowse but with a<br>
different API.<br>
<br>
It would be interesting to hear you opinion so we can improve.<br>
