98	Unable to set Retry-After header with 503 response	phillipoldham.myopenid.com	somebody	"Currently its not possible to use add_header to set a Retry-After header when responding with a 503 header. This causes a problems when trying to inform clients to retry after a timeout when to bring backends back-up after an error.

There are currently work-arounds which involve issuing the headers via a dynamic language (either with a proxy or the perl module) however this may not be possible if these are the cause of the 503.

Suggested resolutions:
Either allow ""add_headers retry-after"" for 50x errors, or change the syntax of error_page to allow one to append ""retry-after x"" to the entry and have nginx add the header."	defect	closed	minor		nginx-core	1.0.x	fixed			n/a	all versions
