ruby on rails - How might Apache cause duplicate requests? -


I have two rail applications that talk to each other. A few times a day requests App A to show a duplicate (or triple / quadruple) in App B. All outbound and inbound requests are logged. Logs show that the app is sending an outbound request and that App B receives two or more requests during the same second.

App B is behind Behind the Apache and Amazon Lowsticks Load Balancer.

I'm not sure where to ask about this issue, to ask about where or even what questions to ask. If you want more data, I would love to provide it. The possibility of retries is the Amazon flexible load balancer or some network component (eg router, for example).

Actually, a idle time is exhausted at some level in the request request chain. If it does not return the appropriate HTTP 5xx status to the time-out customer (for example, it can only shut down the connection quietly), then the source of the timeout and the potentially dependent on the component between the client Decide to try how they are configured.

Tracking below can be very challenging to try which component reasons. My recommendation is to ensure that your Rail app always responds instantly to each other if the requests Can not be completed quickly, so consider a background / voting solution or non-HTTP communication method (for example WebSketts).

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number".

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
