We’re having a sort of an issue with some tracking links.
Some links we track need placeholders like this ##ASPID##, others like this %%ASPID%%. The exact placeholder tag %%ASPID%% will then be replaced by some values, if they exist, so encode them is not an option.
The first case has no problem at all, 302 Redirect, the second one gets stuck in the collector, 400 Bad Request, without the expected redirection.
Take a look:
Anyone able to provide a fix/workaround for this issue?
