Hello; I am working on a project that submits form data asyncronously*. I have to look over the results to figure out what needs to be corrected. The results are in the form of file contents written by php code. Sometime I make changes to the php code that should result in changes to the file. Those changes would be visible by opening and reading the file with my own eyes. But the file is not changed. * 'ajax' submission I figured out that the submissions are be cached somewhere and I have to tell my browser to dump its cache so the revised php code will be reread and the changes applied. So it PHP caching form submissions"? javascript its used to construct and submit the form data and I know that it caches that type of data. That is usually solved by reloading the page from the server. But that is not rereading the php code. system: MAMP on Mac os Sequoia localhost php vers 8.2.20, browser used to test; Firefox Thank you for time and attention JK
