LYNX-DEV Help with address parsing when using proxy

[Doug Kaufman]

Perhaps someone on the list ca explain to me what is going on. This is
probably not specific to lynx, since the same behavior is seen on the DOS
port of 2.8pre.2, on SunOs 2.7.2, and on Netscape4.01 on DOS. I generally
connect through a http proxy, since certain sites are difficult to reach
from my ISP otherwise, but am not behind a firewall. When attempting to
access Alfredo Cole's web site, I get different results, depending on
whether or not the proxy is used, and depending on the exact URL used (2
redirections from the published URL). I suspect that this is either a
misconfigured server at geocities, or a misconfigured proxy at my ISP.

When NOT using the proxy, the page loads normally, after the redirections.
When using the proxy, I get 4 behaviors, as follows:

1. http://www.acyc.com/
I get a page from geocities stating www.geocities.com/~acyc/ does not exist.

2. http://www.geocities.com/~acyc/
I get a page from geocities stating www.geocities.com/~acyc/ does not exist.

3. http://www.geocities.com/%7Eacyc/
I get a page from geocities stating www.geocities.com/Eureka/Plaza/4918/
does not exist.

4. http://www.geocities.com/Eureka/Plaza/4918/
I get the page without problem.  This is the same page I get with
http://www.acyc.com/ when not using the proxy.

There is first a 302 temporary redirection to
http://www.geocities.com/~acyc/ , then a 301 permanent redirection. I
really don't understand the 301 to what looks like the same address in
the trace file, but actually goes to the address in the above paragraph.
The following is a diff of the trace files (from SunOs lynx2.7.2), first
with the proxy, then without. Any insight into what is going on would be
appreciated.
