curl - Remote server returns 404 when requesting an existing url -


i've again got strange problem:

i'm writing crawler index specific site. weeks worked fine , ran problems when sending many requests per hour.

but can't access single page.

but what's stranger: have submit form values via post, server returns 404 error - although url correct.

i implemented many techniques prevent beeing recognized bot: changing user-agent, delays, , i'm sending referer-header pretend form submitted own website.

may again spam- or ddos-protection on server? or there other possible sources of error?

okay, solved it.

a strange behaviour of remote server caused problem: when sending more parameters expected, returned 404 instead of ignoring not needed parameters.
