No, the code that performs the merge doesn't know Cookie from ApplePie. This merge is allowed by the HTTP RFCs, and expected by Apache mods/CGIs/etc. Essentially, any multi-instance requst header fields must be combinable with ",". (insert discussion of different cookie formats) IIRC, by default the WLS cookie parsing (underneath the servlet getCookies() API) doesn't handle this particular merge by default but at least some versions of WLS have an option (some startup property?) to relax the parsing rules and work around this issue, resolving the problem you encountered. I also recall that if you look across a number of different cookie parsers underneath different programming environments you'll see some that relax the interpretation and some that don't. This can be solved by parsing Cookie yourself or convincing getCookies() to do the right thing. (What about storing Cookies in another format which would allow different Cookie headers to be merged in an unambiguous manner? I just don't know the details of the alternative formats.) --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
