Colin Hurley created CXF-6871:
---------------------------------
Summary: Adjust default User-Agent header format to better comply
with HTTP specification
Key: CXF-6871
URL: https://issues.apache.org/jira/browse/CXF-6871
Project: CXF
Issue Type: Improvement
Components: Transports
Affects Versions: 3.1.6, 2.7.11
Reporter: Colin Hurley
Priority: Trivial
The default value CXF sends for the User-Agent HTTP header is formatted as E.g.
{{Apache CXF 3.1.6}}.
According to the HTTP specification, multiple products in the User-Name header
are delimited by whitespace, and a product can optionally indicate its version
by separating the product name and product version with a slash. ??RFC-1945,
Sections 10.15, 3.7; RFC-2616, Sections 14.43, 3.8??
Based on this information, CXF's default User-Agent value is indicating three
products with unspecified versions: {{Apache}}, {{CXF}}, and {{3.1.6}}, rather
than the intended Product Name = {{Apache CXF}} and Product Version = {{3.1.6}}.
I suggest altering the formatting so the default User-Agent for CXF becomes
E.g. {{Apache-CXF/3.1.6}}. This will convey the intended product information
so it semantically complies with RFC-1945 and RFC-2616.
