This option makes a conditional HTTP request for the specific
|
|
|
|
|
ETag read from the given file by sending a custom If-None-Match
|
|
|
|
|
header using the extracted ETag.
|
|
|
|
|
|
|
|
|
|
For correct results, make sure that specified file contains only a single
|
|
|
|
|
line with a desired ETag. An empty file is parsed as an empty ETag.
|
|
|
|
|
|
|
|
|
|
Use the option --etag-save to first save the ETag from a response, and
|
|
|
|
|
then use this option to compare using the saved ETag in a subsequent request.
|
|
|
|
|
|
|
|
|
|
\fCOMPARISON\fP: There are 2 types of comparison or ETags, Weak and Strong.
|
|
|
|
|
This option expects, and uses a strong comparison.
