Hi,
I'm having troubles writing my code which interacts with the Nav OData web services, in particular because of differences between environments.
In short, there are two environments I'm communicating with: Test and Prod, for the same customer.
When I request data from the test environment, I receive a list of items, and each item has an ETag:
"@odata.etag": "W/\"JzU2O2h4WUFBQUNMQVFBQUFBSjcvMVlBU0FCR0FEQUFNQUF3QURFQU13QTJBQUFBQUljUUp3QUFBQUE9MTA7NzI2MzcwNDEzMDA7Jw==\"",
When I request data from the exact same resource in the production environment, I get the ETag a bit differently, i.e. there are two properties this time:
"odata.etag": "W/\"'56%3BhxYAAACLAQAAAAJ7%2F1YASABGADAAMAAwADIANQA5AAAAAIcQJwAAAAA%3D10%3B11808877060%3B'\"",
"ETag": "56;hxYAAACLAQAAAAJ7/1YASABGADAAMAAwADIANQA5AAAAAIcQJwAAAAA=10;11808877060;"
Note: the entities in question are of the same type but contain different data, hence the difference in the ETag values themselves.
I've learned that the difference between the ETags which start with "W/\" and those which don't is that the "W/\" prefix denotes a "Weak" ETag, while the other is a strong ETag.
However, what I haven't figured out is the following:
Is there a resource somewhere which discusses this?
The real reason for my troubles is that I'm writing code which updates said resources. I've managed to get this to work on the test environment, but not in the production environment, and I suspect that the differences listed above may be a part of the reason why, but I cannot be sure until I've solved this.
Regards,
DanÃel
In which format you are retrieving the data, did you try in JSON format and do you see the same difference? is the URL matches except for the server name and instance
