(this signals the end of the headers). What did cache.log say? Regards Henrik -----End Original Message----- Hi Henrik, You are right; the error is because there is no blank line delineating the response headers from the response body. What STABLE release started to enforce this? It must be between STABLE6 and STABLE10. Just curious - does the case of response headers matter at all? It was hard to tell reading the RFCs if the case of the header name was important. Thanks, Ken.
