After turning on logging, the total issued in this message keeps growing and
growing:
org.apache.http.impl.conn.tsccm.ConnPoolByRoute.getEntryBlocking[FINE|feed-processor-16|21:46:47]:
[HttpRoute[{}->http://img.ffffound.com]] total kept alive: 240, total
issued: *160*, total allocated: 400 out of 400
Today it started at 100 and is now 160. the day before it started at 30 and
ended at 100.
There is actually one more method I use httpclient within, it is a little
more complex but still very similar to my other code in its usage of
httpclient. It is below.
public String fetch(String publicUrl, int timeoutMillis, Cookie[]
cookies, Map<String, ?> postData, Map<String, String> headers)
throwsIOException, HttpException
{
HttpRequestBase method;
if(postData == null)
method = new HttpGet(publicUrl);
else
{
HttpPost post = new HttpPost(publicUrl);
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
for(Map.Entry<String, ?> entry : postData.entrySet())
{
if(entry.getValue() instanceof Collection<?>)
{
Collection<?> value = (Collection<?>) entry.getValue();
for(Object v : value)
{
nvps.add(new BasicNameValuePair(entry.getKey(),
v.toString()));
}
}
else
nvps.add(new BasicNameValuePair(entry.getKey(),
entry.getValue().toString()));
}
post.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
method = post;
}
configureMethod(method, timeoutMillis); //sets timeouts, user agent, etc
if(headers != null)
{
for(Map.Entry<String, String> entry : headers.entrySet())
method.addHeader(entry.getKey(), entry.getValue());
}
HttpContext localContext = null;
if(cookies != null)
{
CookieStore cookieStore = new BasicCookieStore();
for(Cookie c : cookies)
cookieStore.addCookie(c);
localContext = new BasicHttpContext();
localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
}
HttpResponse resp = null;
try
{
resp = _httpClient.execute(method, localContext);
}
catch(Exception ex)
{
ex.printStackTrace();
}
int statusCode = resp.getStatusLine().getStatusCode();
if (statusCode != 200)
{
if(resp.getEntity() != null)
{
try
{
EntityUtils.consume(resp.getEntity());
}
catch(Exception ex) {} //dropped
}
throw new HttpException(statusCode, statusCode + " " + publicUrl + "
failed: " + resp.getStatusLine());
}
return EntityUtils.toString(resp.getEntity());
}
