POST /proxy/[port]/hosts is throwing Multiple entries with same key: www.test.com=173.0.92.19 and www.test.com=173.0.0.0, if I set again

[syam palepu]

Hi,

while using the BMP Rest API - POST /proxy/[port]/hosts for remapping the host. I see Multiple entries with same key: www.test.com=173.0.92.19 and www.test.com=173.0.0.0, if I set again with same key.

which mean if I POST  this requset {"www.test.com": "173.0.92.19"} to /proxy/[port]/hosts two times I am getting   java.lang.IllegalArgumentException: Multiple entries with same key: www.paypal.com=173.0.92.19 and www.paypal.com=173.0.0.0

looks like this API is not allowing the multiple keys. 

is there any option to override the existing keys?

Thanks in Advance.

Regards,

syam.

I have found some thing regarding this, but I am not sure whether this is done purposefully.

@Post
	@At("/:port/hosts")
	public Reply<?> remapHosts(@Named("port") int port, Request<String> request) {
	LegacyProxyServer proxy = proxyManager.get(port);
	if (proxy == null) {
	return Reply.saying().notFound();
	}
	@SuppressWarnings("unchecked") Map<String, String> headers = request.read(Map.class).as(Json.class);
	for (Map.Entry<String, String> entry : headers.entrySet()) {
	String key = entry.getKey();
	String value = entry.getValue();
	proxy.remapHost(key, value);
	proxy.setDNSCacheTimeout(0);
	proxy.clearDNSCache();
	}
	return Reply.saying().ok();
	} while remapping the host, we are using the remaphost for each key pair. can't we do the whole map resetting as follows. @Post @At("/:port/hosts") public Reply<?> remapHosts(@Named("port") int port, Request<String> request) { LegacyProxyServer proxy = proxyManager.get(port); if (proxy == null) { return Reply.saying().notFound(); } @SuppressWarnings("unchecked") Map<String, String> headers = request.read(Map.class).as(Json.class); proxy.remapHosts(headers); proxy.setDNSCacheTimeout(0); proxy.clearDNSCache(); return Reply.saying().ok(); } would some one help me clear my understandings and query?

Thanks & Regards,
