Bug ID: 64816
Summary: Headers 'If-Modified-Since' header causes 400 in
8.5.58
Product: Tomcat 8
Version: 8.5.58
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: nityasant...@gmail.com
Target Milestone: ----
Created attachment 37503
--> https://bz.apache.org/bugzilla/attachment.cgi?id=37503&action=edit
Has screenshots where we have 400 errors and 200 success
In the Tomcat 8.5.58 change log we have this - 'Improve the validation of
entity tags provided with conditional requests. Requests with headers that
contain invalid entity tags will be rejected with a 400 response code. Improve
the matching algorithm used to compare entity tags in conditional requests with
the entity tag for the requested resource. Based on a pull request by Sergey
Ponomarev. (markt)'.
We believe this update is causing 400 error in Chrome when caching is enabled
and requests which have 'If-None-Match' and 'If-Modified-Since' headers. When
caching is disabled using Developer tools 400 errors are gone.
