How can I check in NGINX if query parameter in URL was provided. Most examples have specific parameter in mind. I just want to check if any is provided, but I don't know in advance what are the parameter names.

Suppose that the request url is:
http://ip:port/myapp/user/add
How can I get "myapp" in nginx.conf ?
I know /myapp/user/add can be got by using variable $request_uri, but I can't find about the variable that obtains the context of the url.
Many thanks.
I am trying to define dynamic route in Apigee Edge, but not able to define one, any help will be appreciated.
I think you must be referring to the conditional flows in the proxy endpoint, that way you can specify both verb and path to be checked in the preflow.
Please refer to http://docs.apigee.com/api-services/content/flow-variables-and-conditions for more details.
We've got a client that would like to get a response from our server that would look something like that:
http://www.clientDomain.com/tmp?first=a&second=b&link=$$http://www.otherDomain.com/tmp?third=c&forth=d$$
The client doesn't want the link parameter to be encoded.
As far as I'm aware, this is an illegal parameter, that may seems like one is trying to confuse a web server or a router, yet I could not find any documentation to support that. I didn't find any relevant info in the http protocol documentations.
Is that really an illegal parameter? Can you please refer me to a relevant documentation?
Thanks a lot.
See the URL Encoding section here: https://en.wikipedia.org/wiki/Query_string
Which of them is correct definition of URL rewriting?
Shortening of URL for end-user as elaborated here
Appending extra arguments to URL sent to server for session management
I am confused over which one was invented first, and which one should be correct definition of URL re-write?
URL rewriting is simply what its name implies: rewriting/modification of URLs.
This can be used for shortening URLs, and it can be used for appending query parameters, but it’s not restricted to these two use cases.
To make the URL more readable
Example www.abc.com?id=1 rewrite it to www.abc.com/1
I have a service callout in Apigee where instead of hardcoding the Url for the HTTPTargetConnection I want to use a variable for the value of the url.
Example:
http://{request.queryparam.url}
This is giving me a 404 Not Found error but if I hardcode the same value that is passed as a queryparam it works fine and calls the target service and return a response.I am not able to find any details on this in docs.Please help me out.Thanks.
This is potentially a bug.
Please attach a policy of your own in the target.xml request part of the application which assigns the target.url variable with your variable of choice. You can use assign variable or javascript or python as you wish for this policy.
EDIT:
What I answered above applies for target callouts. Not service callouts. To better understand the issue I request you to post the debug.xml in a pastebin or something similar.
