BTW, I’m also written the backend. There are some examples on the web about solving this problem in the backend using cookies to keep track of the state. I’m give it a try.
Thanks for the reply. I was thinking about that, but in this specific case, changing back button behavior seem to improve user experience. See, for instance, Lemmy. IIRC, after submitting a new post, you are redirected to the post page you just submitted. If you press browser back button, you are taken to the community index page, not the submit form. How does Lemmy achieve this? Is it one single page, which content is changed by Javascript or, it is like my application, in which a full reload of the page is done?
Thanks. It seems these functions are useful in a SPA context? Since I’m reloading every page (I’m using plain HTML for most of this application) these functions seem not to be really useful for the purpose I wrote. Maybe I’m doing something wrong?
Yeah, I ended up using awk, which solved my problem perfectly. I was just curious if I could do that with sed, but it seems too complicated. Thank very much, guys!
