dynamic target URL with proxy: issue with http

yanngrostete-1 · 08-20-2019 07:00 AM

I have a proxy which modify dynamically the target URL thanks to a JS policy in the target pre-flow.

To reach this target, I have to pass through an http outbound proxy. So the property "use.proxy" is set to true.

If the targeted URL is HTTPS, it works.

if the targeted URL is HTTP, it doesn't work (gateway timeout).

I do some tests to understand where is the problem:

I tried to replace the target endpoitn by 2 service callout policies (one with http and one with https as the scheme cannot be in the variable) and I have the same result.

I tried without the use.proxy and it works with an http url (but the outbound proxy is mandatory in my case)

I tried with the right URL put directly as the target and it works - something like this:

<HTTPTargetConnection>
    <URL>http://example.com</URL>
    <Properties>
        <Property name="use.proxy">true</Property>
    </Properties>
</HTTPTargetConnection>

So it seems there is this problem only for the combination: dynamic target URL + http scheme + outbound proxy.

Could you help me to find a solution?

Thanks

Does the outbound proxy support a http target?

Yes, it does: if I put the http url directly in the URL element with use.proxy=true, the request is well done. But if the same URL is set through a JS policy in the pre-flow of the target, it fails. This problem occurs only with http url.
