Hi, I'm using Squid 2.6.STABLE17 on Redhat & Windows, configured in a chain of peers with custom auth & external acl helpers that manipulate the proxyauth credentials/header. This works fine when the user:passwd string is less than 256 bytes (prior to base64-encoding), but I noticed that squid truncates anything larger than that. I didn't find any stated header size limit in the RFCs (2616, etc.), and I'm wondering if this is an arbitrary, static limit imposed by squid? If at all possible, I need to increase that limit to 1 KB, and I'm wondering if this can be done without patching the source. I didn't see anything obvious in the config file or the docs. Thanks for any assistance that you could provide. Glenn Zazulia
