connectionsPerRoute has no impact on Connection when using http component
hi,
In my camel route i am using http component to connect to a HTTP service, I
have the connectionsPerRoute query parameters set on the url as per the
documentation. but I see that always 2 connections are established to the
HTTP service even though I am sending many concurrent requests to the route.
I added a couple of print statements to get pool stats for every
connect() call, I always see 2 connections getting established, I also
verified there is always 2 number of connections in the ESTABLISHED state
on the HTTP service side.
PoolStats-->[total kept alive: 0; route allocated: 2 of 2; total allocated:
2 of 20]
in the PoolingHttpClientConnectionManager code, I see that the CPool is
initialized with defaultMaxPerRoute as 2.
this.pool = new CPool((ConnFactory)new
InternalConnectionFactory(this.configData, connFactory), 2, 20,
timeToLive, timeUnit);
Shouldnt this be overridden with the connectionsPerRoute value? is
there any way to configure thie connections Per route configuration?
any help would be appreciated.

Hi
Try with a newer Camel version such as 3.20.1, or 3.18.x.
We do not support old Camel versions which are EOL.

hi Claus,
thanks for responding.
i tried setting the connections per route configuration as a component
option, but still, i see only 2 connections being established to HTTP
service.
these 2 connections are the httpClient library's default value. camel is
not able to overwrite this. i am on camel 3.7.0.
i have added the component option below, can you please point out if I
have missed out anything?
<bean id="http" class="org.apache.camel.component.http.HttpComponent">
<property name="maxTotalConnections" value="22"/>
<property name="connectionsPerRoute" value="22"/>
</bean>

Hi
It looks like setDefaultMaxPerRoute is invoked later that changes this
value.
Also you should not use query parameter as the http client may be
already created if you use http component elsewhere, favour set the value
on the component level
