Hello,
I have an important question about the use of a 'GDAL_HTTP_HEADER_FILE'.
If I request a WFS with "OGR_WFS_PAGING_ALLOWED=ON" and use a header file
for authentication, will the header file be read with every new page?
I am wondering how I should deal with an expiring bearer token (validity
5min) with a very long lasting query (>5min).
Is this for one WFS service, or many ?
Assuming you are consuming the data promptly and aren't overloaded,
I would discuss this with the WFS service; you probably aren't
the only one having this issue. If sending the data takes longer
than the life of the token, they need longer-lived tokens.
Sorry I can't help with your actual questions.
Questions:
Does ogr2ogr query the header file again for each new page?
Can I possibly set the authentication for every single requested page?
Is there another way to deal with expiring tokens?
Michael
PS:
I use Java and start the apps via the ProcessBuilder.
If the header file is re-read for each page, I could update it accordingly
(preferably without conflicts due to simultaneous reading and writing ;o)
).
