Question

Does someone know if I set　MaxPerRoute and MaxTotal of PoolingHttpClientConnectionManager to "0" like below, what will happen?

PoolingHttpClientConnectionManager.setMaxPerRoute(0)
PoolingHttpClientConnectionManager.setMaxTotal(0)

Answer 1

An exception

throw new IllegalArgumentException("Max value may not be negative or zero");

for both methods, check the org.apache.http.pool.AbstractConnPool class source code.
