in Mozilla there are two variants in the field analysis: POST and GET

Method : POST
Link: http://www.eatonpowersource.com/cross-re...e/results/
Parameters
Criteria.SiteSearchTerm
Criteria.CurrentPageNumber=1
Criteria.FilterOptions.SortBy=CompetitorPartNumber
Criteria.FilterOptions.SortOrder=Asc
Criteria.CompetitorPartNumber=0330D0
Criteria.FilterOptions.PageSize=25

and
Method: GET
Link:
http://www.eatonpowersource.com/cross-re...9680055925

Параметры
Criteria.SiteSearchTerm=
Criteria.CurrentPageNumber=1
Criteria.FilterOptions.SortBy=CompetitorPartNumber
Criteria.FilterOptions.SortOrder=Asc
Criteria.CompetitorPartNumber=0330D0
Criteria.FilterOptions.PageSize=25
_=1569680055925

If I send a request query with GET parameters and method, I get the following

If I send a request query with POST parameters and method, then I get
either 404 - page not found
or error 500
