Why the images is compressed?
Hello All,
I apply the compression profile to a VS.
As far as I know, because the image was already compressed itself, they don't have to be compressed. Right?
Hmm. However the images are compressed.
So I exclude the image but they still are compressed.
I tested with two profile as follows;
ltm profile http-compression httpcompression_test_1 {
app-service none
buffer-size 40960
content-type-exclude none
content-type-include { text/ "application/(xml|x-javascript)" }
defaults-from httpcompression
min-size 512
selective enabled
uri-exclude { .*\\jpeg .*\\png .*\\gif .*\\jpg }
uri-include { .*\\html .*\\htm .*\\js .*\\css .*\\asp .*\\aspx }
}
ltm profile http-compression httpcompression_test_2 {
allow-http-10 disabled
app-service none
browser-workarounds disabled
buffer-size 40960
content-type-exclude { image/ img/ }
content-type-include { text/ "application/(xml|x-javascript)" }
cpu-saver enabled
cpu-saver-high 90
cpu-saver-low 75
defaults-from httpcompression_jobkorea_1
gzip-level 1
gzip-memory-level 8k
gzip-window-size 16k
keep-accept-encoding disabled
method-prefer gzip
min-size 512
selective enabled
uri-exclude none
uri-include { .* }
vary-header enabled
}
The images still are compressed.
