Hi, I have an off-topic networking problem. If anyone knows a better forum for me to ask this please let me know as it is doing mu head in. When I am working on a site, I edit the files then upload them to the server and look at them in a browser. All good so far... the problem is that frequently bits fail to load (css, images, the page itself). This only happens when I open them from the office, and other sites seem to be fine. It seems to get worse if I am frequently making minor changes to a file. Any ideas on how I can track down what is causing this? I have looked using ethereal and get a lot of retransmissions, but I dont know why. Any help would be greatly appreciated as it gets very frustrating trying to test sites when I have to reload the page 4 times to do so. Ben.
