Depends on how the applet is written, I'd guess. Not sure though. However, if compression is very important and accepting gzipped content is not possible with an applet, you could gzip the files beforehand so that the files that are served are gzipped already (even though there's no Accept-Encoding header). This would of course require that the applet decompress the text before processing, but at least you'd cut down on your network traffic...<br>

Hi ALL,<br>
<br>
I am very new to nginx, and I found the nginx is the perfect tool for me to do reverse-proxy while compressing the data. I have successfully configured the proxy_pass and gzip configurations and it is working as I expected in test environments.<br>
<br>
We have web servers which streaming text data through java applet to the end users. Nginx is act as a reverse-proxy for back-end web servers; once the java applet loaded on the FireFox or IE browser it keep receiving data without any issue. But the problem is those text data won't get compressed though text, images etc loaded to the browser get compressed. I can compress data off the applet but once it send it to java applet, won't get compressed.<br>

It seems that java applet does not send the "Accept-Encoding: gzip"<br>
request header.<br>

I ran Wireshark to analyze the data on java applet and firefox browser to check what type of header request they send. Here are my findings.<br>
<br>
>From browser:<br>
GET /mbr/ds.aspx?SID=1F5AAWQWQWSA1 HTTP/1.1<br>

Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2<br>

<br>
I think java applet don't sends Accept-Encoding header to the server; and this should be the problem. I am not a java expert and the new question, is this possible with a java applet set Accept-Encoding request header...?<div class="im">

<br>
BTW why do you compress image/gif image/jpeg image/png ?<br>
This is just waste of CPU time.<br>

<br></div>
Yes, I have to avoid them, my concern is huge text data.<br>
<br>
Any advice on the new question is really appreciated.<br>
