![]() ![]() If you send me the version of Chrome you downgrade to in order to get the project to work, I might be able to give you some more insights into what exactly is going on when you upgrade Chrome, but the best course of action here is probably to reload the firmware on your ESP with a bigger allocation for header processing. If I had made my project name much longer, or had a longer email address, then I would have tripped the issue. ![]() The resulting packet was 507 bytes, just 5 bytes short of the limit. For the example app I built, the package name was appinventor.ai_ewpatton.WebviewHeaderTest. , which is likely bound to be longer than 3. The values, including the \r\n characters are as follows:ĥ2. X-Requested-With: 3īased on what I’ve found about the ESP32 HTTP server processing of headers, the request line doesn’t count against the 512 bytes of headers, so we can start counting from the start of the Host field. 96 Mobile Safari/537.36Īccept: text/html,application/xhtml xml,application/xml q=0.9,image/webp,image/apng,/ q=0.8,application/signed-exchange v=b3 User-Agent: Mozilla/5.0 (Linux Android 8.1.0 Pixel Build/OPM1.171019.012 wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome. It may differ slightly from your phone, but I think the point should generally be the same: Here’s an example of the packet sent from my phone. I used Wireshark on the server to capture incoming packets to the python server. This means that the HTTP request line and the Host headers are exactly the same length as in your scenario. The IP address of the machine had the same length as the one given in your pictures. Here are the results of my analysis.Ī python server running on port 8000 with a single file stream. I poked around a bit and tried to mimic this as best I could given that I don’t have a ESP32 Cam. In fact, here is an explanation written by MIT Guru Evan Patton on our old Google Groups Forum: ![]()
