Hi,

I have some serious troubles getting gzip to compress text/html and  
text/plain content.

I’ve put a nginx as revproxy to Jenkins. Jenkins return headers like  
“Content-Type: text/plain;charset=UTF-8” and “Content-Type:  
text/html;charset=UTF-8”. Even with all fancy stuff like enabling gzip  
for 1.0 proto, gzip\_proxied any and so on, no output is compressed.

Tested version 1.5.4.

– Piotr.

Do you have gzip\_types properly set?

Maxim, thanks for your time and willing to help.

False bug report.

After doing some tests I found out that if I check localhost it does  
gzip, but if I go thru full ip/domain it does not - I had $http\_proxy  
variable set and the proxy server was not providing me gzipped content.  
Sorry about the noise.

– Piotr.

I believe I do. I tried quite a lot of combinations, also, text/html is  
default on and cannot be removed if I understand it corrently so it  
should work just as-is. I tried adding even full string like  
“text/html;charset=UTF-8” still no luck.

Could you please show the configuration you use, and  
an example request which shows the response isn’t gzipped?
