+synopsis: Fix handling of ETag header for remote packages
+packages: cabal-install
+prs: #9116
+issues: #9113
+
+description: {
+
+Remote packages will now be cached regardless of the capitalization of the
+"ETag" header. Previously remote packages would not be cached if the header
+name did not match exactly. Now they will be cached even if the header's
+capitalization is different.
