Currently Apache/2.2.3 on an older suse linux. If that helps I could try Apache/2.2.10 on another system, but that would require some more setup work. According to docs the options I use should be available for 2.2.3.
options you've replaced with '...' in the snippet you
SSLEngine on
SSLCipherSuite ...
SSLCertificateFile ...
SSLCertificateKeyFile ...
posted? Is it only using SSL that you see delays? Do you have a SSLRandomSeed directive?
I did not really deep test SSL compared to normal HTTP as for SSL the client infrastructure is missing and I did not want to start development until I'm sure the general system works.
But as the normal HTTP already delays too much I'm pretty sure SSL wont be better (as it is a layer on top and thus should have same limitations). The problem is, that the NTRIP caster sends e.g. a TCP packet where I have a chunky header and e.g. 70 characters. From apache I only get a combination of more than 5 to 10 of these chunks. When each chunk means one second, than the delay gets large.
The caster HTTP answer also contains following lines to prevent caching,
"Cache-Control: no-store,no-cache,max-age=0\r\n"
"Pragma: no-cache\r\n"
but this does not help as well.
