Creating a HTTP connecting and keeping it open to recieve data
java,http,apache-httpclient-4.x
With traditional HTTP technology you can only do polling, which means you request "do you have more data" from the server. The server than can wait for some time when it has no data (this is called "long polling"). This should be a short time so it works with stuff...
how to implement long-link or half-long-link by HttpClient?
apache-httpclient-4.x,android-async-http
If your so-called "long-link" or "half-long-link" means "keep-alive", then I thought I got a solution. There is a header called "Connection" which has two arguments to be selected: "Keep-Alive" or "close". In http 1.0, it's "close" by default. But in Http 1.1, "Keep-Alive" is the default value. So, if you...
Unable to download image from Google Cloud Storage url with Android

Why is the constant HTTP.UTF_8 deprecated?
Since Java 7, Java provides the StandardCharsets class for getting the Charset object for a few standard character sets. These are: ASCII, ISO-8859-1, UTF-8, UTF-16, UTF-16BE, and UTF-16LE. That's the alternative. There's no longer a point in re-declaring the String name of the character set in an HTTP class....
DefaultHttpClient blocking different threads
android,multithreading,apache-httpclient-4.x
Are you sure it's the HttpClient and not the AsyncTask that can only have one running instance? If I recall correctly, the default threadpool for AsyncTask (unfortunately) has 1 thread associated with it which means only 1 active AsyncTask can run at any given time. To fix, you can try...
How to force Apache HttpClient / HttpConnection to absolutely close tcp connection?

Using HttpAsyncClients: keep connection alive for long time
java,http,apache-httpclient-4.x
The re-use of the same instance of HttpAsyncClient is highly recommended. HttpAsyncClient will not get 'stale'. One only needs to close HttpAsyncClient once there are no more requests to be executed (for instance, in case of application shut down).
Getting results of WFS request to GeoServer as UTF-8
java,utf-8,apache-httpclient-4.x,geoserver
Instead of passing in a BasicResponseHandler, use the HttpClient.execute(HttpUriRequest) method which returns a HttpResponse and then use EntityUtils.toString(HttpEntity, "UTF-8"), pseudo: HttpResponse r = httpClient.execute(httPost) String utf8encodedEntity = EntityUtils.toString(r.getEntity(), "UTF-8"); ...
How to configure the number of allowed pending requests in Apache async client
java,apache,httpclient,apache-httpclient-4.x

How to execute url which has xml data as query parameter through Apache HttpClient?
java,http-post,apache-httpclient-4.x,apache-commons-httpclient
Honestly, I don't think you want to try and pass XML through your URI. There are several things to consider. One, some servers will block long URIs (Google first result: http://www.checkupdown.com/status/E414.html ). Next, you would want to "encode" the URI so it escapes all of your chars that are not...
Use of non-ascii credentials not working in httpclient 4.3.x

'Improperly formatted request' error after switching from Commons HttpClient to HttpComponents

Try using 'browser compatible' mode instead of 'strict' when constructing the request entity with MultipartEntityBuilder UPDATE 1: "Content-Type: multipart/form-data[\r][\n]" This is clearly wrong (boundary attribute is missing) and likely to be reason for the request being rejected.

Apache HTTP Client: build simulator using multithreaded environment
java,multithreading,apache-httpclient-4.x,java.util.concurrent
You can toggle re-use of connections within the pool using the builder's setConnectionReuseStrategy. The DefaultConnectionReuseStrategy will re-use connections whenever possible, but the NoConnectionReuseStrategy will close all connections returned to the pool. I used these connection re-use strategies in reverse: in production no re-use was set (to ensure proper load-balancing -...

How to solve org.apache.http.NoHttpResponseException
Finally figured it out on my own. If the previous response gives header, "connections=close", next request always gets this exception. So, when seeing this header, put 2 more lines conManager.closeExpiredConnections(); conManager.closeIdleConnections(0, TimeUnit.SECONDS); to let connection manager close the connection so that the connection won't be used by the next request....
Apache httpclient: why doesn't retry when timeout
