Content-length header incorrect with cgi and deflate combination

• Additional Comments From bruno@wolff.to 2002-12-22 19:53 ------- I think I have something that will point out where I am seeing the problem. In mod_deflate.c there is code to not due compression for subrequests. I think this check should be extended to not do it for internal redirects. (I am not sure why the check that the request doesn't already have a gzip encoding doesn't catch this.) I checked r->next to see if there will be more processing after this request is completed. I am not sure this is correct, because the .h that defines record_rec has a comment that this link refers to external requests. I suspect that that is a typo. Anyway the patch seems to work for my problem. I will let you know if this fixes the IE problem when I hear back from the person who has been having problems with compressed responses. The diff versus mod_deflate.c follows:
