User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050910 SeaMonkey/1.0a Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050910 SeaMonkey/1.0a A page in question is generated by a local database monitoring tool and is not accessible from the outside world, thus no url, but I've pasted it to 'Additional information' box, hope it's ok. As server is in LAN I've added it to preferences.advanced.proxies.no proxy, which SLOWED page loading considerably. This page has 4 charts wich are re-generated each time the page is loaded (src="/websmon?host=moscdev1&service=psd-dyn&page=recs&graph= ...), generation of each image takes a second or two. When host is not in 'no proxy' string all 4 images are loaded simultaneously and the whole page is loaded in 1-2 seconds. When host is in 'no proxy' images are loaded one by one and the whole page is loaded in 5-7 seconds. Apparently adding host to 'no proxy' somehow disables parallel image retrieval.

Your proxy might be a caching proxy. What is the exact hostname in the URL for the images, and the exact string you have in your no proxy config?

(In reply to comment #1) > Your proxy might be a caching proxy. > No, I bypassed the caching proxy and investigated this problem using junkbuster (ad removal HTTP 1.0 proxy). BTW may be this is important: mozilla disk cache is turned off (0 size) as I have squid runnig locally. > What is the exact hostname in the URL for the images, it is in the attached file - no hostname, relative. src="/websmon?host=moscdev1&service=psd-dyn&page=recs&graph=daily" > and the exact string you > have in your no proxy config? I put hostname of the server in question to the start of no proxy string: moscdev1, .....
