It may be time for any with a gmail account to clean it out completely and then go into settings and set gmail to forward all incoming email to another account on another provider. ___ Lynx-dev mailing list Lynx-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/lynx-dev
Re: [Lynx-dev] what controls the redirect limit?
An engineering principle is once required capacity is found, build in 3 times that capacity for future unexpected events. If you can get it, try for 60.

Re: [Lynx-dev] what controls the redirect limit?
Can speak to no one else, but in the cases I am encountering, there is progress being made. Speaking personally raising it from 10 to say 20, would likely solve the issue for me at least.

Before upping the limit in this specific case, you should make an attempt to see if it is actually making progress on each redirect, rather than looping.

[Lynx-dev] Google vs redirection limit [was Re: what controls the redirect limit?]
> I admit I'm surprised that gmail found a way to break even a limit of > 10. So was I, a little. But this _is_ Google we're talking about. Turns out I still have a trace log. Here's what it shows, with details that might contain private data (mostly encoded stuff) replaced with "redacted". Start: http://mail.google.com/ 301 to /mail/ -> http://mail.google.com/mail/ 302 to https://mail.google.com/mail/ 302 to https://accounts.google.com/ServiceLogin?service=mail=true=false=https://mail.google.com/mail/=1=1=default=2=1=1# 200 OK (user interaction here) POST to /signin/v1/lookup 302 to https://accounts.google.com/signin/challenge/pwd/1?continue=https%3A%2F%2Fmail.google.com%2Fmail%2F=mail=1=1=false=1=GlifWebSignIn=default=redacted%3D%3D=redacted 200 OK (user interaction here) POST to /signin/challenge/pwd/1 302 to https://mail.google.com/accounts/SetOSID?authuser=0=https%3A%2F%2Faccounts.google.ca%2Faccounts%2FSetSID%3Fssdc%3D1%26redacted%3Dredacted%26continue%3Dhttps%253A%252F%252Fmail.google.com%252Fmail%252F=redacted=redacted%3D%3D 302 to https://accounts.google.ca/accounts/SetSID?ssdc=1=redacted=https://mail.google.com/mail/=redacted%3D%3D 302 to https://mail.google.com/mail/ 302 to https://mail.google.com/mail/u/0/ 302 to https://mail.google.com/mail/u/0/?ui=html=g 302 to https://mail.google.com/mail/u/0/h/redacted/?zy=g=1 200 OK Interestingly, the log I have ends there. Either Google had changed something between my having the issue and the taking of that trace or the redirection count limit applies even when user interaction interrupts the flow of redirections; I count only 10 redirections across the whole session. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTMLmo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B ___ Lynx-dev mailing list Lynx-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/lynx-dev

Re: [Lynx-dev] what controls the redirect limit?
Oh but no. I barely have access to my gmail via lynx here as it is, plus I pay for two accounts here, including having my site hosted here for a reason. I like Jude's idea, that way everyone who is a customer benefits. On Sat, 28 Aug 2021, Mouse wrote: Karen Lewellen writes, in reply to the patch I posted, My hope is that there is something I can influence, as I use Lynx on a service, not as a part of my own computer. So I am unsure just where that would go exactly? What I gave is a change to the source. If the "service" in question lets you compile software yourself, or copy in software compiled elsewhere, then you could compile your own version of lynx with that change - or any others you want. At least, in principle. I don't know you well enough to know whether you have the skill (or inclination!) to do that, even if there aren't technical restrictions in the way. Jude DaShiell writes that The REDIRECTION_LIMIT variable is the last line in lynx.cfg. This indicates that the answer depends on which version of lynx is in use, because the version I was working with, the version that patch applied to, had the limit of 10 hardwired into the code, not user-configurable. That's apparently changed since then, so it depends on whether you're using a version before or after that change. (It's a good change; if I'd been more comfortable in the innards of lynx back in 2018, or if I'd been more ambitious, I would have done something like that myself value rather than just raising the hardwired limit from 10 to 25.) Even if your lynx has that configurability, though, depending on just what "service" means here, you may or may not be in a position to use your own lynx.cfg. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B ___ Lynx-dev mailing list Lynx-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/lynx-dev ___ Lynx-dev mailing list Lynx-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/lynx-dev

Or ask the administrator to make the change as it seems like a fine one
for everyone.

Good news here. The REDIRECTION_LIMIT variable is the last line in
lynx.cfg. I just set mine to 1. For anyone using lynx on a service,
copying lynx.cfg to a user directory then running
lynx -c ./lynx.cfg will use your copy and not the system's copy of
lynx.cfg. You would need to chmod lynx.cfg so you could edit it once in
your user directory though.

[...], I reach a lynx error that says something like maximum number

What in Lynx controls the number of redirects the browser considers
safe, and how can I increase that number?
A few years back, I was working at a job that, "thanks" to a confluence
of various reasons, ended up with me wanting to use lynx to read
Google-hosted mail through their webmail interface.
I promptly ran into the ten-redirection limit.
As for how I dealt with it, turns out I still have the commit:
