RE: [flexcoders] Re: HTTPService multiple requests not being sent?
Injecting a current client-side timestamp into an outbound request is a good
way to avoid Http response caching if you don't control the server.
If you do control the server, you should consider configuring it to set HTTP
no-cache headers in these responses to suppress caching.

I have "heard" that POSTed requests do not cache. I use POST
exclusively, and have never had any caching issues.

Re: [flexcoders] Re: HTTPService multiple requests not being sent?
If you're GET requesting a URL that points to dynamic content that changes
with every request, whoever is in charge of the server really should be
setting no-cache, and they'd probably appreciate being notified of what is
in effect a bug in the service. Adding a timestamp get parameter just smells
like we're back in the 90s doing PHP :D

Re: [flexcoders] Re: HTTPService multiple requests not being sent?
I do have control of the server and I'm using GET requests. I've also done
the setting headers. None of that did any thing. I am sending requests to a
single Servlet. I've setup a message to print in the log if any request
comes in and it shows the client never made a request. I think this is
truely the client caching. I'll try the post method, but I think I did that,
not sure. However like I said I created the Servlet and it's not getting any
hit from the client at all. It's like the client just looks at the request
params and sends the last requests data, if the params match. I'm not sure
the Seth Hodgson thing would apply as my requests are several seconds apart.

Re: [flexcoders] Re: HTTPService multiple requests not being sent?
You won't get the information in the servlet if your server is caching a
text response. The browser may only be doing a head request, or it may be as
you suspect doing nothing. Download a debugging proxy like Charles (
http://www.charlesproxy.com/ ) to be sure. It'll tell you exactly what's
going on.
